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  • Outdated software versions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 Where can I get help with the import process?
Answer The Composr documentation provides extensive information. Additionally, you can seek assistance from experienced Composr developers, including the Composr team if your project allows for professional support.
Question Can I switch from a third-party forum to Conversr (Composr's built-in forum)?
Answer Yes, if an importer exists for your current forum software, you can switch to Conversr during the import process. Composr will handle the forum driver switch and remap user IDs, but it's recommended to double-check permissions afterward.
Question How does the HTML website importer work?
Answer The HTML website importer is an advanced tool for migrating static HTML websites to Composr. It analyzes the HTML structure to create zones, Comcode pages, and a basic template. It also attempts to fix links and file paths for Composr compatibility.
Question What is a Composr import session?
Answer Import sessions track the progress and ID remapping for each import, allowing you to merge multiple sites or resume interrupted imports. This is particularly useful when merging multiple Composr sites into one.
Question Are there any limitations to importing forum data?
Answer Yes, some limitations exist, particularly with specific forum platforms.
  • General: Private messages are often combined into private topics.
  • phpBB: Usergroup configuration and HTML entities may require manual adjustments after import.
  • vBulletin: Calendar recurrences, ratings (karma), and 'goes to coventry' are not imported perfectly. Attachments may need to be extracted directly from the live database due to potential corruption in SQL dumps.
  • Simple Machine Forum: Banning features may not import perfectly due to differences in how Composr handles bans.
Question Where can I find the import functionality in Composr?
Answer Navigate to Admin Zone > Tools > Import.
Question What data formats can Composr import?
Answer Composr primarily uses database connections for importing. However, it also supports neutral data formats like CSV spreadsheet files and importing downloads from a directory.
Question Can I import data from other platforms into Composr?
Answer Yes, Composr offers importers for several popular platforms:
  • Forum Software: Invision Board, MyBB, phpBB, Simple Machine Forum, vBulletin
  • Content Management Systems: WordPress
  • Special Importers: HTML website importer, Composr merge (for merging another Composr site)
Question How do I move my Composr website to a new server?
Answer Moving a Composr site involves transferring both the files and the database.

Files:
  • On the old server, ZIP the entire Composr directory.
  • Download the ZIP file to your computer.
  • Upload the ZIP file to the new server using SFTP/FTP.
  • On the new server, unzip the file.

Database:
  • On the old server, create an SQL dump of your database using the mysqldump command or phpMyAdmin.
  • Download the SQL dump file.
  • If your URL is changing, search and replace the old URL with the new one in the SQL dump file.
  • Upload the SQL dump file to the new server.
  • Restore the database on the new server using the mysql command or phpMyAdmin.

Important Steps:
  • File Permissions: After transferring files, ensure correct file permissions are set on the new server. You can use the fixperms.php script, the upgrader script, or manually adjust them.
  • Configuration: If database settings are different on the new server, update the _config.php file or use the config_editor.php script to change the settings for both the site and forum databases.
  • Base URL: If your URL has changed, update the base URL setting in the Installation Options editor (config_editor.php).
  • Caches: Clear the block cache using the upgrader.php script.
Question Can I integrate third-party JavaScript libraries into Composr?
Answer Yes, you can integrate third-party JavaScript libraries using various methods:
  • Direct reference by URL: Include the library's URL in your theme's HTML.
  • Composr's JavaScript API: Use Composr's API for organized inclusion and potential future compatibility benefits.
  • Manual integration: Directly include the library's code in appropriate template files.
Choose the method best suited for your needs and technical proficiency.
