The forum base URL should be a URL prefix to your forums without a script name. For example, http://forums.example.com is correct, while http://forums.example.com/index.php is incorrect. You can fix this using the config_editor.php script and then clear the Comcode page cache.
Most Composr resources with commenting enabled create comment topics in the configured comment forum. If the forum uses BBCode, Comcode features not supported by BBCode may not display correctly. Moderate comments from the forum as you would any other topic.
It's not easy to switch forums after installing Composr. The member and usergroup IDs referenced by Composr would lose their association. Check the "Importing data into Composr" tutorial for more information on this.
Conversr is Composr's built-in forum system. It offers seamless integration, allowing you to use Comcode for forum posts, a unified Admin Zone, shared themes and templates, and innovative features like Private Topics and in-post whispers. Using a third-party forum can be clunky and may lead to maintenance headaches.
Composr supports several forum drivers, including Invision Board, phpBB, myBB, vBulletin, Burning Board, and Simple Machine Forum. If your forum is not listed, professional developers can add support. Composr also provides converters for migrating from these forums to its own forum system, Conversr.
What are the PHP requirements for running Composr?
Answer
Composr requires PHP 7.2 or higher, but versions not officially supported by PHP developers are discouraged. The maximum tested version is PHP 8.3.
Required PHP extensions:
GD2 (gd) with PNG and JPEG support
MySQL extension (mysqli or pdo_mysql)
XML extension (xml)
Multibyte String (mbstring)
cURL extension (curl)
JSON support (usually available by default)
Sodium (libsodium)
ZIP extension (zip) if ZIP file support is needed
Additional recommendations:
posix extension for permission checks
zlib extension for faster upgrades, compressed backups, and page compression
ctype extension for slightly faster performance
IMAP extension (imap) for managing newsletter bounces
OpenSSL extension (openssl) for encrypted CPFs, DKIM, and SSL certificate expiry checks
Pspell (pspell) or Enchant (enchant) extensions for spell checking
Ensure the following PHP settings are configured:
File upload size limit of at least 5MB (or higher as needed)
Maximum execution time of at least 30 seconds
Memory limit of at least 128MB
The installer will warn you if any critical functions have been disabled via disable_functions or other PHP modifications. Avoid web hosts that heavily restrict standard PHP functionality.
To uninstall Composr, access the uninstall.php file in your web browser, enter your administrator password, and follow the prompts to remove the database data. Afterward, you can safely delete the Composr installation directory.
What are the recommended web hosting options for Composr?
Answer
Choosing a web host is crucial. Avoid the cheapest options and look for hosts with recent positive reviews and minimal credible complaints. Ensure they meet Composr's requirements, including adequate disk space, no restrictive file size limits, and support for required PHP extensions.
Composr is compatible with various hosting control panels like Plesk and cPanel, and works on Windows, Linux, or Mac OS servers.
Yes, you can install Composr on a Windows desktop using software packages like WampServer, XAMPP, EasyPHP, or ampps for simplified setup. Alternatively, you can manually install Apache, PHP, and MySQL, following the instructions provided in the respective documentation. Remember to configure file permissions appropriately and ensure the webserver isn't accessible from outside your network.
What is a banner wave, and how is it different from a banner rotation?
Answer
A banner wave displays all banners within a specific type as a single advertising block, similar to a list of sponsors. In contrast, a banner rotation randomly displays banners from a set based on factors like display likelihood.
You can add a banner wave using the main_banner_wave block and configure it to show a specific number of banners or all banners within a type.
What is a banner network, and how can I create one?
Answer
A banner network is a system for exchanging banners between websites. You can create a banner network in Composr by associating banners with specific websites.
When a site joins your banner network, you provide them with an iframe code to display banners from your rotation. Composr uses a "hit balancing" system where sites in the network receive banner impressions based on the clicks they generate for other sites in the network.
Yes, by enabling the "Permissions" configuration option in the Admin Zone (Admin Zone > Setup > Configuration > Feature options > Banners), you can control which usergroups can see individual banners. This feature allows for banner targeting and prevents inappropriate banners from being shown to specific audiences, such as adult banners to minors.
What are the different types of banner deployment agreements?
Answer
There are three types of banner deployment agreements:
Permanent: These banners are always displayed as long as there is available space.
Campaign: These banners have a limited number of impressions or clicks before they stop displaying. They can be associated with specific campaigns and can have their hits increased if needed.
Default: These banners are displayed only when there are no permanent or campaign banners available to show.
The system displays permanent and campaign banners with a 50:50 split.
What should I do if URL Schemes are not working properly?
Answer
If URL Schemes, which rely on web server rewrites, are not functioning correctly, you can disable them using the http://yourbaseurl/config_editor.php script. Enable the option "Whether to block the URL Scheme (mod_rewrite)" to override the main configuration setting.
How can I reset a forgotten account password in Composr?
Answer
If you have access to phpMyAdmin:
Access the f_members table.
Find the row corresponding to the user whose password needs to be reset.
Edit the row, setting m_pass_hash_salted to the new password using MD5 encryption, clearing m_pass_salt, and setting m_password_compat_scheme to 'md5'.
If you have FTP access:
Obtain your IP address.
Edit your _config.php file, setting $SITE_INFO['backdoor_ip'] to your IP address. This enables a temporary backdoor login for your IP address, bypassing security restrictions.
Remove the backdoor entry after logging in and resetting the password through standard means.
Caution: Using the backdoor method is a security risk and should be done with extreme caution.
My Composr installation seems corrupted. How can I repair it?
Answer
Composr offers several tools and methods for repairing corrupted installations:
Integrity checker: The upgrader tool, accessible via http://yourbaseurl/upgrader.php, includes an integrity checker that identifies outdated or corrupted files.
MySQL table repair: The Admin Zone > Tools > Cleanup tools provides access to MySQL table repair functionalities. Alternatively, use phpMyAdmin or your web host's database management tools for more direct control.
Safe Mode: Access safe mode via the bookmarked link from the setup wizard or by adding &keep_safe_mode=1 to any website URL. This disables custom themes and caching, helping isolate problems caused by themes or custom code.
