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.
Many web hosting control panels include built-in backup features that operate at the system level, often offering higher reliability than web-based scripts. Ensure you back up both files and the database.
For database backups, you can use tools like phpMyAdmin, which allows you to export your database as a .sql file.
Composr offers a built-in backup addon accessible from Admin Zone > Tools > Backups. You can choose between full, incremental, and database-only backups.
Full backup: Backs up all files and folders within the Composr installation directory, including the database.
Incremental backup: Backs up only new or changed files since the last backup, resulting in smaller backup files.
Database backup only: Backs up only the database.
The addon allows scheduled backups or manual backup generation. It is recommended to download backups to a location outside your web server for better security.
Note: The Composr backup addon is limited by server-side PHP capabilities and might not always be reliable. Consider using alternative backup strategies offered by your web hosting control panel for increased reliability.
Disasters like hard disk failures, data corruption, and unexpected errors can happen at any time. A good backup strategy helps you recover your website and its data in case of such events. Backups can also help you roll back to a previous state if needed, such as after a failed upgrade or accidental changes.
How can I control the privacy of member profile fields?
Answer
You can control the privacy of member profile fields through the "Member privacy controls" configuration option.
If you enable the "Extended privacy option control", you can fine-tune visibility settings for each field. Otherwise, you can set simple access levels (e.g., not at all, to members, to friends, to everyone) for each field.
What is the difference between a Composr member and an author?
Answer
A member is someone who has created an account on your Composr website and can log in. They have a unique member ID and username, and can interact with the site's features.
An author is someone who creates content for the site. They may or may not be a member. For example, you might have an author who submits articles via email but never actually visits or joins the website.
What advanced techniques are available for dealing with persistent spammers who repeatedly create new accounts?
Answer
Composr's advanced banning features target sophisticated human spammers. Automatic bans can be configured to block users based on specific strings in their posts, while reasoned bans display customized messages to banned users, potentially deterring them. These measures, coupled with the ability to investigate users via IP address analysis, offer robust tools for managing persistent threats.
You can configure advanced banning under Admin Zone > Security > Configure advanced banning.
How does Composr handle user banning and what options are available?
Answer
Composr offers various banning mechanisms. You can ban members by editing their accounts (ban member tick box), preventing logins while still allowing guest access. IP address banning blocks access from specific IP addresses or ranges (Admin Zone > Security > Members > Investigate user to see their IP addresses and flag certain ones for banning). You can also restrict member submissions, or you can effectively "suspend" users by assigning them to a usergroup with minimal privileges (e.g. probation).
What is the "Warn Member" form and how can I use it to handle rule violations?
Answer
The "Warn Member" form provides a centralized interface for addressing user misconduct. You can issue formal or off-the-book warnings, apply punitive actions like IP bans, usergroup changes, or probation, and even delete content or charge points. This form allows you to document reasons for actions, improving transparency and consistency in moderation.
This tool can be accessed on a member's profile as staff, under Audit > Warn member. You can also review their warnings history on their "Standing" tab.
Composr logs IP addresses for various actions like guest posting, page views, and content submissions. This data helps identify potential spammers and track user behavior. The "Investigate user" module provides tools to analyze IP addresses and gather additional information about suspicious activity.
