Question What are cleanup tools in Composr and how do I use them?
Answer Cleanup tools assist with website maintenance by deleting unnecessary data and optimizing database tables. They are divided into "De-cachers" and "Optimizers". You can access them through:

Admin Zone > Tools > Cleanup tools.
Question How can I access PHP-Info in Composr?
Answer PHP-Info provides a comprehensive overview of your PHP configuration. You can access it within Composr by navigating to Admin Zone > Tools > PHP-Info / Server Checks.

This page also provides additional useful server information.
Question What is the purpose of the Health Check feature in Composr?
Answer The Health Check feature in Composr proactively identifies potential issues that may affect your website's performance, security, and overall health. It performs various checks and alerts you to problems like:
  • Broken links and forms
  • Security vulnerabilities
  • Outdated software versions
  • Server performance issues
  • Email configuration problems

The Health Check can be run manually or scheduled to run automatically and send e-mail notifications of results.
Question How can I use Content Delivery Networks (CDNs) to enhance my website?
Answer CDNs improve website performance by serving content from geographically distributed servers, reducing latency and server load. You can leverage CDNs for your Composr website by:
  • Configuring the CDN option in Composr with a comma-separated list of CDN domain names.
  • Ensuring your files are mirrored on the CDN servers.
  • Utilizing the CDN_FILTER directive and symbol to control what content is served via CDN.
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 resources are available to help me navigate these legal and social challenges?
Answer Composr offers various resources, including tutorials on accessibility, staff management, and general website dos and don'ts. You can also consult external resources like the COPPA website and Wikipedia for more in-depth information on specific laws and regulations. Remember that seeking legal counsel may be necessary for complex situations.
Question What are some social considerations for running a website with community features?
Answer Managing a community involves addressing social issues like child protection, free speech, discrimination, and abuse. Establish clear policies on these matters, including content moderation guidelines and procedures for handling feedback. Consider the diverse personalities and potential vulnerabilities of your users.
Question What are my legal responsibilities regarding illegal content posted by users?
Answer While "safe harbor" laws offer some protection, you are still obligated to take down illegal content upon becoming aware of it. Implement measures like content checks, clear rules prohibiting illegal uploads, and liability disclaimers. The level of responsibility varies depending on the severity of the content, from copyright infringement to more serious criminal content.
Question What steps should I take to make my website accessible?
Answer Website accessibility is essential for inclusivity and may be legally required under anti-discrimination laws. Composr is designed to meet high accessibility standards, but you need to maintain this when creating content or modifying templates. Following WCAG guidelines is crucial, and you can find more information in the accessibility tutorial.
Question How can I ensure my website complies with email marketing laws?
Answer Email marketing laws like CAN-SPAM protect recipients' rights to unsubscribe. Your website must include a clear 'List-Unsubscribe' header in every email, offer an easy unsubscribe process, and respect unsubscribe requests promptly. Composr provides built-in mechanisms, including an unsubscribe endpoint and support for the List-Unsubscribe header, to facilitate compliance.
Question What are my responsibilities regarding user privacy?
Answer You must have a comprehensive privacy policy that details the personal data you collect, its usage, and if it's shared with third parties. Laws like GDPR have strict requirements, including logging data access, data purging, and security measures. California law mandates specific elements in your policy, like handling "Do Not Track" requests and a clear process for communicating changes.

Composr has an automatic Privacy Policy generator block to help you get started. This is used by default.
Question How can I create effective website rules?
Answer A well-defined rules page is crucial for setting expectations for user behavior and outlining consequences for violations. It should cover a range of offenses with appropriate punishments, reference relevant laws, and assign legal responsibility to users. Composr provides default rules pages that can be customized, and this page is displayed to users upon joining the site.
Question What are the key legal considerations for running a website?
Answer Several legal aspects need careful attention when operating a website, especially for large or corporate sites. These include establishing clear rules and terms of service, adhering to privacy laws like GDPR and California's regulations, managing personal data responsibly, complying with email marketing regulations like CAN-SPAM, ensuring website accessibility, addressing eCommerce regulations, and understanding liability for content and user actions.
Question How do data-tpl and data-view behaviors work in Composr's JavaScript?
Answer Composr uses data-tpl and data-view behaviors for associating HTML templates and JavaScript views, respectively. This facilitates clean separation of presentation and logic:
  • data-tpl: Used with the $cms.behaviors.initializeTemplates function and PARAMS_JSON tempcode directive to bind JavaScript logic to HTML templates.
  • data-view: Used with the $cms.behaviors.initializeViews function to associate JavaScript view classes (inheriting from $cms.View) with specific HTML elements.
Question What are the advantages of using Composr's JavaScript libraries?
Answer Composr's JavaScript libraries like $cms, $util, and $dom offer several advantages:
  • Organization: They provide a structured way to access Composr-specific functionalities, avoiding global namespace pollution.
  • Abstraction: They encapsulate common tasks, simplifying DOM manipulation, form handling, and interaction with Composr's UI.
  • Consistency: They offer a consistent API across different parts of Composr.
