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 are "breadcrumbs," and how can I customize them?
Answer
Breadcrumbs are a navigation aid that shows the user their current location within the website's hierarchy. In Composr, breadcrumbs are customizable through an XML file.
You can override default breadcrumbs using "match-keys" to target specific pages and define the desired breadcrumb structure. This allows you to adjust the breadcrumb trail to better match your website's organization.
To edit, go to Admin Zone > Structure > Configure breadcrumb overrides.
How can I control which panels are displayed on specific pages?
Answer
Panels are the areas around your main content area where you can place menus, blocks, and other dynamic elements. You can control panel visibility using display rules within your panel's Comcode:
{+START,IF,{$NEQ,{$PAGE},example_page_1,example_page_2,example_page_3}}
... panel content ...
{+END}
This example prevents the panel from showing on pages named "example_page_1," "example_page_2," and "example_page_3."
What is a "page-link," and how does it differ from a URL?
Answer
A page-link is a Composr-specific way to reference a page or screen within your website. It's a simplified, local representation of a URL, independent of the URL scheme you might be using.
For example, the page-link site:downloads:browse:10 points to the download category with ID 10 in the site zone. This page-link remains consistent even if your URL scheme changes the way URLs are structured. Page-links also do not consider monikers, so if a URL moniker changes, page-links will stay the same.
This is a powerful feature as you can use the Comcode [page="page-link"]Page title[/page] tag to generate URLs of local content. And these will always work regardless of URL scheme or moniker.
How do menus work in Composr, and can I customize them?
Answer
Composr has a flexible menu system that can be customized to your needs.
Default Menu: Generated automatically from the Sitemap, reflecting the structure of your content.
Editable Menus: You can create and fully customize these menus, adding links to specific content or external websites.
Menus can be added to panels (sidebars, headers, footers) or embedded directly within Comcode pages. The menu editor provides tools for adding branches, setting captions, tooltips, and URLs, and even defining context-sensitive behavior using "match-keys."
What are "zones" in Composr, and what are they used for?
Answer
Zones are like sub-sites within your Composr website. They provide a way to organize content and apply different settings, like permissions, themes, and navigation. Some default zones include:
Welcome Zone: The initial landing page, often used for login/signup.
Site Zone: Your main website content, with features for viewing, submitting, editing, and deleting content on the member level.
Admin Zone: For site administrators to manage the website.
Content Management Zone: Where content is added, edited, and deleted, typically by site staff.
Forum Zone (if using Conversr): Houses the forum section of your site.
What happens when I add a new usergroup to a third-party forum integrated with Composr?
Answer
If you are not using Conversr as your forum, Composr won't automatically assign any permissions to the new usergroup. To rectify this, you can use the "Absorb usergroup-permissions" feature in the Admin Zone. This tool allows you to copy the permissions from an existing usergroup to the newly created one, ensuring consistent access and functionality.
What are some security considerations regarding super-moderators and super-administrators?
Answer
While super-moderators have extensive access to manage your site, certain sensitive privileges are reserved for super-administrators. This includes the ability to impersonate other users, execute arbitrary code, and view private content. These restrictions help prevent potential privilege escalation and ensure the overall security of your website. Exercise caution when granting super-moderator status and trust only reliable individuals.
What are some useful tools for debugging permission issues?
Answer
Composr provides a couple of tools to help pinpoint permission problems:
FirePHP: This browser add-on allows you to view detailed logs of permission checks performed by Composr. By analyzing these logs, you can identify which checks are failing and adjust your settings accordingly.
Permission Check Logging: Enable logging of failed permission checks to a file (data_custom/permission_checks.log). This provides a persistent record of permission issues that you can review and troubleshoot.
How can I test if my permission settings are working correctly?
Answer
Composr's "SU" feature allows administrators to temporarily assume the identity of another user, enabling you to experience the site as they would. Simply enter the desired username in the "SU" box in the footer. You can also use "Guest" to browse as an unauthenticated visitor. Remember that using "SU" doesn't accurately reflect online status and retains administrator access to sensitive areas.
