Short Description This is the main website for Composr CMS version 11. It runs the latest build of v11. Currently it is just a placeholder but will soon replace compo.sr when v11 becomes stable.
Question Should I use the bleeding edge releases or the git repository?
Answer

That depends on several factors. Here are some pros and cons of each:

Bleeding edge releases Git repository (v11 branch)
Easier to set up and use, and does not require knowledge of git Harder to set up and use unless you are familiar with git; must routinely run the file integrity check, database upgrade tool, and check database schema tools in the upgrader after pulling
More stable, but less frequent updates Less stable, but more frequent updates (almost daily!)
Only contains core code and addons unless you manually install non-bundled addons; non-bundled addons must be manually updated Contains all core code and non-bundled addons; non-bundled addons are updated with pulls (though you will need to check file/database integrity often and check blocks/modules for available upgrades)
Ability to test the upgrader / upgrading between new v11 versions Not able to effectively test the upgrader because git pull might load in and update new code early before the release is available
Always contains the latest files.bin and db_meta.bin because these are compiled with every release Does not always contain the latest files.bin and db_meta.bin. Therefore, file and database integrity may report false-positives.
Intended for general user testing Intended for developers / developer testing:
* special run-time checks are enabled for extra debugging (if the .git directory exists in the install)
* contains the automated test suite for running tests

Question Can I switch a v11 install from git over to using the releases from composr.app?
Answer

It is not recommended you do this because you may run into issues. For example, some changes were made in crypto_master.php and data/upgrader2.php prior to the first v11 alpha. These changes will result in a broken upgrade unless you already pulled these changes from git. Similar situations could happen in the future as well.

It is recommended you either discard the git install and use a fresh install from the Downloads, or to maintain a git install and a bleeding-edge release install separately. Do not combine the two.

Question Should I update my non-bundled addons after updating to a newer release of version 11?
Answer

Absolutely! Frequent changes may be made to both bundled and non-bundled addons. Bundled addons will be updated via the upgrader. For non-bundled addons, you will have to update them through the addons management screen (Admin Zone > Structure > Addons). You will be informed which ones need updated.

Once version 11 reaches release candidate, we do not expect frequent updates to non-bundled addons anymore. But it is still good practice to check after every update.

Question Can I upgrade a version 10 site to version 11?
Answer

Yes, for basic non-custom v10 sites. However, expect some issues to arise in the process. And please report those issues to the tracker.

For v10 sites with non-bundled addons or customisations, upgrading to v11 will likely break the site until you update the non-bundled addons or temporarily remove the customisations.

We aim to have the upgrader fully functional for a large majority of types of sites and for sites using non-bundled addons by the time version 11 reaches release candidate stage.

We do not recommend upgrading production v10 sites at this time until v11 reaches stable.

Question Can I upgrade a previous version 11 release to a newer one using the upgrader?
Answer

Yes (probably). Always remember especially during alpha and beta phases that things can break. Please make backups first. And let us know on the issue tracker if an issue occurs.
 

Note: You cannot upgrade from 11 alpha to 11 beta without first upgrading to 11.alpha4 (if you are not already on 11.alpha4).

Question How Do I Import Images in bulk into a Gallery?
Answer You can import images in bulk using a CSV file. The file should be named descriptions.csv and placed in the uploads/galleries directory. The first column should contain filenames (without the path), and the second column should contain descriptions. The filenames should correspond to images also located in the uploads/galleries directory. Composr will automatically match the descriptions to the images during import.
Question What Image and Video Formats are Supported?
Answer Images:
  • .jpg/.jpeg: Highly compressed, best for photos due to minimal noticeable quality loss.
  • .png: Good compression with no quality loss, ideal if bandwidth isn't a concern.
  • .gif: Limited to 256 colors and poor compression. Better alternatives are video or APNG.
Note that Composr does not support SVG because hackers can leverage the XML-like structure of SVG files to compromise a website.

Videos:
  • .mp4 (h.264 aac encoding): The recommended format, widely supported.
  • .mov (h.264 aac encoding): Identical to .mp4.
  • .webm: Supported natively in most browsers, but requires plugins for Internet Explorer/Microsoft Edge and Safari.

Other formats, while they may work, are generally discouraged due to compatibility issues and lack of consistent addon or browser support.
Question What are Composr Galleries?
Answer Composr Galleries are a system for storing, organizing, and displaying images and videos. They function like categories, allowing you to group related media together. Galleries can be structured hierarchically, with sub-galleries nested under parent galleries, similar to a folder system. Each gallery has settings that control its appearance and behavior.
Question How are forums structured in Composr?
Answer Composr forums are organized hierarchically:
  • Forum Groupings: Broad categories that contain forums.
  • Forums: Contain topics related to a specific subject.
  • Sub-forums: Forums nested under other forums, providing further categorization.
  • Topics: Threads of conversation containing a series of posts.
  • Posts: Individual messages within a topic.
Question How do I debug email integration issues?
Answer
  • Email Tracking: Composr marks emails as read when processing posts. Marking an email unread will trigger re-processing.
  • Log File: Create an empty file named data_custom/mail_integration.log to capture detailed log data for troubleshooting.
Question How can I control who can post in my forums?
Answer You can manage posting permissions using Composr's usergroup system.

  • Forum View Access: Determine which usergroups can view each forum.
  • Privilege Overrides: Grant or deny specific privileges (e.g., posting) to usergroups within a forum.
  • Bypass Validation: Allow trusted members to post without moderation (or vice versa, require validation for certain usergroups).
Question What special features does Composr's Conversr offer compared to other forum software?
Answer
  • Advanced Polls: Blind polls, forcing or setting of default options, and point-weighting.
  • Private Topics: More sophisticated than traditional private messages.
  • Forum Introduction Questions: A flexible way to control access and encourage engagement (e.g. forum-specific rules or forum passwords).
  • Cascading Topics: Pinned topics that appear in multiple forums.
  • Integrated Moderation: Streamlined moderation tools within the forum interface.
Question How do topic polls work?
Answer Topic polls are a powerful tool for gauging opinion within discussions. You can:

  • Control Result Visibility: Choose whether results are visible before voting.
  • Require Topic Reply: Force users to reply to the topic before voting.
  • Show Voter Identities: Optionally display which members voted for each option.
  • Allow Vote Revocation: Let voters change their vote while the poll is open.
  • Set Voting Close Time: Define a specific date or time for the poll to close.
  • Restrict Selections: Limit the number of options voters can choose.
  • Allow Guest Voting: Enable voting for unregistered users.
  • Weight Votes by Points: Give more influential members greater voting power (requires the points addon).
Question What are the different types of posts in Composr forums?
Answer
  • Regular Posts: Standard posts made by members within a topic.
  • Quick Replies: Shorter replies made directly from the topic view.
  • Anonymous Posts: Members can choose to post anonymously, appearing as a guest. Staff can track the actual user if needed.
  • Emphasised posts: Posts made by staff (or marked by staff) which are highlighted to draw attention as they are important.
  • Whispers: Private messages embedded within public topics, allowing for side conversations.
  • Private Topic Posts: Private messages sent between specific members (e.g. an on-site "inbox").
Question Can I integrate email with my forums (mailing list)?
Answer Yes, you can enable email integration for each forum individually. This allows members to post and receive updates via email.

Requirements:
  • PHP IMAP extension installed
  • System scheduler (Cron) running
  • IMAP-compatible mail server

Recommended:
  • Mail server enforces SPF and DKIM for email validation
  • Mail server limits email size to prevent abuse
  • System scheduler runs frequently (e.g., every minute) so members get prompt updates
