Question How can I control who can view specific pages or categories?
Answer You can manage access control for zones, pages, and categories primarily through the Permissions Tree Editor (Admin Zone > Security > Permissions Tree Editor). This tool provides a central location to set view permissions for different usergroups. You can also edit individual zone and category permissions through their respective editing interfaces, but the Permissions Tree Editor offers a more streamlined and efficient approach.
Question What is the difference between access permissions and privileges in Composr?
Answer Access permissions control whether members of a certain usergroup can view specific areas of your site, such as zones, pages, and categories. A member only needs one of their usergroups to have access permission to view the content. But permissions work on a deny-first policy; if one of the permissions applicable to viewing something is denied for a usergroup, then the whole thing is denied for that usergroup (e.g. even if a download itself grants access, access will be denied if its category denies access).

Privileges, on the other hand, dictate what actions a usergroup is allowed to perform across the website, like using advanced Comcode or bypassing the word filter.
Question How can I change the news archive display to show summaries instead of just headlines?
Answer By default, the news archive screen shows only headlines. To display summaries like the news block, add :inline=1 to the page-link. For example, if your news archive page-link is site:news, modify it to site:news:inline=1. This will show summaries instead of just the headlines in the archive view.
Question What are Trackbacks and how do they work in Composr?
Answer Trackbacks are a blogging feature that creates a link from an article on one blog to an article on another, acting as a citation mechanism.

How Trackbacks Work:
  • The original article includes a "trackback" link in its HTML.
  • When another blogger writes an article referencing the original, their software uses the trackback link to inform the original site.
  • Composr receives the trackback and displays a list of articles linking back to the original.

To enable trackbacks, go to Admin Zone > Setup > Configuration > Feature options and check the "Trackbacks" option. You can then enable trackbacks for individual content items.
Question How can I filter the news archive to show specific content?
Answer The news system allows advanced filtering:
  • Blog vs. Non-Blog Posts: Choose to display blog posts only, regular news posts only, or both.
  • Category Filtering: Limit results to specific news categories.
  • Double Filtering: Apply a second category filter for a two-level categorization system (useful for large sites).

These filters are controlled through parameters passed to the news blocks and carried through navigation links. When viewing a news post, you can also filter by the categories associated with that post.
Question How do I display external RSS feeds on my Composr website?
Answer Composr offers two blocks for displaying RSS and Atom feeds in a news-like format:
  • main_rss block: Suitable for main content areas
  • side_rss block: Designed for sidebars and smaller spaces

To add a block, use the Block Construction Assistant or insert the following Comcode into your page:

[block="http://example.com/feed.xml"]main_rss[/block] [block="http://example.com/feed.xml"]side_rss[/block]
Replace "http://example.com/feed.xml" with the actual feed URL.

Important: Exercise caution when using external feeds. Ensure the source is trustworthy, as malicious feeds can contain harmful code.
Question What are RSS/Atom feeds and how do they benefit my website?
Answer Feeds, in formats like RSS and Atom, are XML files that syndicate your website content, making it accessible beyond your website. They can be viewed using feed reader applications (e.g., Feedly, Vienna) or integrated into other websites or web browsers.

Composr supports both RSS and Atom for syndicating news and other content. While RSS is more common, Atom is a cleaner, standardized format. Both effectively share your content updates.

Benefits:
  • Wider audience reach: Your content becomes accessible to those using feed readers and aggregators.
  • Content repurposing: Other websites can incorporate your feed, increasing visibility.
  • Increased traffic: Users discovering your content in feeds may visit your website directly.
  • Staying on top: Those who use your RSS feeds will see when you post new news articles.
Question What are Personal Categories/Blogs in Composr? How do I create one?
Answer Composr allows members of permitted usergroups to have their own personal news categories, also known as "blogs". These blogs appear as a tab on the member's profile (Conversr-only) and may also appear in the main news block depending on your configuration.

To create a blog, a member simply adds a news post and selects their personal category. If the category doesn't exist, it will be automatically created upon submission.

A dedicated "Blogs" CMS module (Admin Zone > Content > Blogs) is available if the "Separate blogs" configuration option is enabled. This simplified module focuses on blog posting and can be used to restrict members from submitting to general website news.
Question What is "pinging" and how does it work in Composr?
Answer In blogging, "pinging" is an automatic notification sent to blog search engines and other services when you publish a new post. Composr can automatically ping services defined in Admin Zone > Setup > Configuration > Feature options. These services then index your new article, making it searchable.

A default ping service (http://pingomatic.com/ping/?title=title&blogurl=url&rssurl=rss) is pre-configured to relay your ping to numerous other services.

You can customize the ping URL with these placeholders:
  • title: The article title
  • url: The article URL
  • rss: The URL of your news RSS feed

Pinging only occurs for news categories accessible to the public (guests).
Question How do I schedule a news post to be published at a specific time?
Answer Once you have enabled the system scheduler (requires the Composr calendar and commandr addons), an advanced scheduling option will appear when adding or editing news posts. By setting a future date and time, your post will remain unvalidated until the chosen time, at which point it will be automatically validated and published.

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.
