Question	What is rate limiting and how can I enable it in Composr?
Answer	Rate limiting prevents server overload by restricting the number of requests allowed from a single IP address within a specific timeframe. To enable Composr's built-in rate limiting, add the following to your _config.php file: Code (`PHP`) $SITE_INFO['rate_limiting'] = '1'; $SITE_INFO['rate_limit_time_window'] = '10'; $SITE_INFO['rate_limit_hits_per_window'] = '5'; This configuration limits each IP to 5 requests every 10 seconds. This feature generates soft errors early in the process before Composr fully loads.

Question	How can I reduce disk activity to improve performance?
Answer	If your hard disk is slow, you can implement the following settings in your _config.php file to minimize disk access: $SITE_INFO['disable_smart_decaching'] = '1'; $SITE_INFO['no_disk_sanity_checks'] = '1'; $SITE_INFO['hardcode_common_module_zones'] = '1'; $SITE_INFO['prefer_direct_code_call'] = '1'; $SITE_INFO['charset'] = 'utf-8'; $SITE_INFO['known_suexec'] = '1'; $SITE_INFO['dev_mode'] = '0'; $SITE_INFO['no_extra_logs'] = '1'; $SITE_INFO['no_extra_bots'] = '1'; $SITE_INFO['no_extra_closed_file'] = '1'; $SITE_INFO['no_installer_checks'] = '1'; $SITE_INFO['assume_full_mobile_support'] = '1'; $SITE_INFO['no_extra_mobiles'] = '1'; Note: These settings override default behaviors and may have unintended consequences. Use with caution.

Question	What is static caching and how do I enable it?
Answer	Static caching drastically improves performance by serving pre-generated pages to bots and guests. This works because these users typically don't require dynamic content. To enable it: Go to the Installation Options editor (`yourbaseurl/config_editor.php`). You will need your maintenance password. Activate the static cache option. Composr intelligently determines what to cache, and you can further control this via options within the Installation Options. Be aware that enabling static caching may disable eCommerce features for guests unless specifically configured.

Question	What are Composr caches and how do they improve website performance?
Answer	Composr utilizes various types of caches to enhance performance by storing pre-calculated results and reducing repetitive tasks. These caches include: Language cache: Eliminates the need to parse language files on each page load. Template cache: Avoids reparsing template files repeatedly. Comcode page cache & Comcode cache: Reduces the need to parse Comcode pages and general Comcode usage. Block cache: Caches blocks based on their parameters, minimizing execution. Theme image cache: Prevents redundant searches for theme images. Values caches: Stores calculated values like member post counts. Persistent cache: Keeps frequently used data in memory for faster access. Advanced admin cache: Allows admins to view cached pages while the server generates updates. Static cache: Serves static pages to bots and guests, bypassing much of the framework. Self learning cache: Optimizes resource loading by learning which resources each page requires.

Question	How can I troubleshoot notification problems?
Answer	If you're having issues with notifications, here are some troubleshooting steps: Check Email Logs: View the email log (Admin Zone > Audit > E-mail queue/log) to see what notifications have been sent. Use the SU Feature: Impersonate a member using the SU feature (described in the "Testing access and privileges" tutorial) to view their notification settings and confirm they are set up correctly. Enable Carbon-copy Email: Configure a "Carbon-copy e-mail address" in the configuration settings to receive copies of all outgoing emails, including notifications. This helps you monitor email delivery. Verify System Scheduler: Ensure the system scheduler is configured correctly if members are not receiving digest emails. Check Digest Settings: Confirm that "Enable digest notifications" is enabled in the Messages configuration settings. Review "Safety listing limit": If a notification has too many categories, members might not see the full selection tree. Adjust the "Safety listing limit" in the configuration settings if necessary.

Question	Can I control which notifications members receive?
Answer	Yes, you can control notification settings through two mechanisms: Notification Defaults: You can set default notification preferences for all members. You can enable or disable specific notifications and choose the delivery method (Admin Zone > Setup > Notification defaults). Notification Lock-down: You can force members to receive or prevent them from receiving certain notifications (Admin Zone > Setup > Notification lock-down). This allows you to enforce specific notification policies and manage email volume.

Question	What notification options are available to members?
Answer	Members can choose from a wide range of notifications, including: Content Updates: Notifications for new or updated content, such as news articles, forum posts, and gallery images. Private Messages: Alerts for new private messages received. Friend Requests: Notifications for new friend requests. Administrative Actions: Alerts for actions taken by site administrators, such as account approvals or content moderation decisions. Members can choose to receive notifications via: Email: Notifications sent directly to their email address. Digest Email: Combined summaries of activity sent in batched emails. This requires the system scheduler and the digest e-mails configuration option to be enabled. Private Topics: Notifications delivered as private forum topics. SMS: Notifications sent as text messages (requires configuration and incurs costs). Web Notifications: Real-time alerts displayed within the Composr interface.

Question	Can I share content like news and banners across the M.S.N.?
Answer	Yes, you can share news by placing it on the central site and using RSS blocks on satellite sites to display it. Banners can be shared by adding them to the central site and configuring satellite sites to use the central site's banner.php script.

Question	What should I consider when managing usergroups for subcommunities?
Answer	Rank ladders: Use the default rank ladder for main site ranks and secondary usergroups for subcommunity memberships. New member status: Set default usergroups for new members to grant them initial access while allowing removal if necessary. Leadership: Assign leaders to usergroups to allow members to manage subcommunities. Clubs: Consider using Clubs for member-driven subcommunities with their own forums.

Question	What are Composr Clubs and how are they useful for subcommunities?
Answer	Clubs are special usergroups in Conversr (Composr's forum system) designed for creating subcommunities. They come with their own dedicated forums and are managed by members, taking pressure off site staff. Key features: No special permissions by default, simplifying permission management. Members can join and leave like regular usergroups. Provide a dedicated forum for the club.

Question	How do I set up the system scheduler in Composr?
Answer	The system scheduler is crucial for scheduled tasks like sending notifications, running backups, and processing reports. To set it up, you need to schedule a system-level task to run the data/cron_bridge.php file at least every 10 minutes. This links Composr's scheduler with your server's scheduler (like Cron on Linux). Composr can often detect the correct command to use for your setup. You can check by visiting `http://yourbaseurl/data/cron_bridge.php?query_mode=1`, which should display the suggested Cron command. Note that you may need to replace the php command with the absolute path to PHP if you cannot use the php command directly. If your hosting doesn't support Cron or scheduled tasks, you can enable scheduled tasks to run when visitors access your site. Navigate to Admin Zone > Setup > Configuration > Performance options and check "Web requests run scheduled tasks". Keep in mind that this method relies on visitor traffic and isn't as reliable as a dedicated scheduler. Alternatively, consider using external services like EasyCron, setcronjob.com, or onlinecronjobs.com. These services allow you to schedule calls to the data/cron_bridge.php script by URL at specified intervals.

Question	What are the different security levels in Composr's Setup Wizard and what do they affect?
Answer	Composr offers five security levels in the Setup Wizard: Minimum, Low, Medium, High, and Ultra High. Each level sets various security configurations that you can later customize under Admin Zone > Setup > Configuration. The security levels influence settings such as: Content Security Policy Session expiry time Password reset process Password expiry days Minimum password length and strength Login error secrecy IP strictness for sessions Cryptographic ratchet CAPTCHA usage Brute force threshold Audio CAPTCHA URL Monikers .htaccess restrictions on maintenance scripts Enquiry on new IP addresses The higher the security level, the more stringent the security measures, with Ultra High offering the most robust protection but the most potential inconvenience to users. Generally, you should use these settings depending on your site: Minimum: Very bare-bones informational-only sites Low: Sites which do not allow public registrations and do not use eCommerce but have content managed by different staff, and are not concerned with privacy or data Medium: Sites with social features / public accounts but do not use eCommerce. High: Sites which use eCommerce. Ultra High: Sites containing very sensitive data, such as but not limited to cybersecurity sites, government departments, banks, healthcare, etc.

Question	How do I change my website's logo?
Answer	You can change your site's logo manually or by using the Logo Wizard. To change it manually, go to Admin Zone > Style > Themes. Choose "logo/-logo" from the dropdown list, which represents the logo for the Welcome Zone and any zone without a specific logo. Replace the current image by uploading a new .jpeg, .gif, or .png file. Ensure that the 'Name' field remains unchanged.

Question	What are Composr addons and how do I manage them?
Answer	Composr is built using a series of addons that provide different functionalities. All "bundled" addons are installed by default. Once you are familiar with Composr, it's recommended to remove any bundled addons you don't need to simplify your site and prevent accidental exposure of unconfigured features to visitors (the Setup Wizard can also uninstall these addons based on your preferences). You can manage addons by navigating to Admin Zone > Structure > Addons. Uninstalled addons are archived and can be restored later, but any associated data will be permanently lost. Composr also offers non-bundled addons. These addons are not bundled because they are not considered mainstream, rely on third-party services, haven't been vetted to Composr standards, or don't fully conform to those standards. You can install non-bundled addons by going to Admin Zone > Structure > Addons, scrolling to the bottom and clicking "Import non-bundled addon(s)". You will need to browse to the addon file and click the import button. Once imported, review the warnings and proceed to install the addon. You can also download and import addons from this website under the Downloads section.

Question	What are some of the default Comcode pages in Composr?
Answer	Composr includes several default Comcode pages, each serving a specific purpose: home (Welcome and Site zones): The default front pages for the respective zones. sitemap (Welcome zone): Displays the sitemap, typically generated automatically. _rules (Welcome zone): Outlines the site rules, also displayed during registration. The "rules" page (no underscore) is a wrapper for this page. privacy (Welcome zone): Provides privacy policy information. By default, this is generated automatically with Composr's privacy policy generator block. 404 (Welcome zone): The page shown for 404 errors (page not found) and includes a sitemap. help (Site zone): Contains general help information. userguide_comcode (Site zone): A basic guide to Comcode for users. Remember that you can edit these default pages or create entirely new ones to tailor your site's content to your specific needs.

Question	How do I hide a Comcode page from the sitemap?
Answer	If you want to prevent a Comcode page from appearing in your sitemap, you can simply prefix its name with an underscore (_). For example, pages named "_test" or "_example" would be excluded from the sitemap. Note that this generally does not hide the page from your site itself (to do that, use the validation addon to turn validated to "OFF" for the pages); it only hides them from the sitemap / search engines.

Question	Can I organize Comcode pages in a hierarchical structure?
Answer	Yes, Composr allows you to simulate a hierarchical structure for your Comcode pages using multi-part paths in the page monikers. By editing the page monikers to include slashes (e.g., "about/team"), you can create a virtual directory structure within a single zone, enhancing your site's organization and navigation.

Question	How do I embed content from other modules into a Comcode page?
Answer	You can use various blocks to embed content from different modules: main_content block: Allows you to feature individual entries from modules/content like news or articles. main_multi_content, main_cc_embed, main_gallery_embed, main_news blocks: Enable you to pull in and display multiple entries based on categories or other criteria. main_include_module block: Provides a powerful way to integrate any module screen directly into a Comcode page.

Question	What is the difference between blocks and boxes in Composr?
Answer	While both terms may seem similar, they have distinct meanings in Composr: Blocks are functional units that generate dynamic content or provide specific features. They don't inherently have a visual form and their output can vary widely. Boxes are a visual design element in Composr, essentially containers that visually group content on a page and often with a title at the top. In practice, blocks often place their content within a box, but this isn't a requirement / standard.

Question	Can I customize the appearance of blocks?
Answer	Yes, you can customize the appearance of blocks by editing the associated templates and CSS. Each block typically has a corresponding template file (e.g., BLOCK_MAIN_NEWS.tpl for the main_news block) that controls its HTML structure. You can modify this template to change the layout and styling of the block's output. An easy way to do this is through the template editor in Admin Zone > Style > Themes, and click edit templates for the relevant theme.
