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:
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.
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.
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.
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.
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.
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.
Gift points are a separate points balance that can only be sent to other members as gifts. They cannot be spent directly or used in escrow transactions.
Gift points are earned daily based on usergroup membership and replenish independently of the regular points balance. When a member sends gift points, they become regular points for the recipient.
Yes, members can send points to each other as a token of appreciation, reward for a service, or as part of an agreement using the Points Escrow system.
Points are typically awarded immediately upon content submission to encourage participation. However, forum posts requiring validation only earn points after approval to deter spam. To further encourage high-quality content, consider using the "awards" addon to reward exceptional contributions.
Can I reward members who use specific browsers or operating systems?
Answer
Yes, Composr allows you to configure bonus points based on browser/platform criteria. You can set bonus points for members using Open Source browsers, specific operating systems, or even those who have enabled privacy features like "Do Not Track" (DNT) or "Global Privacy Control" (GPC).
What's the difference between points balance and rank points?
Answer
Points balance refers to the number of points a member currently has available to spend. This is the 'liquid' currency they can use for various actions.
Rank points represent the total points a member has accumulated throughout their time on the website. These points determine the member's rank, which can grant access to additional privileges and act as a status symbol.
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:
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.
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.
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.
