Question	Can I display different content to different usergroups?
Answer	Yes, you can achieve this by leveraging Tempcode within your templates. By using conditional statements like `{$IS_IN_GROUP}` and `{$HAS_PRIVILEGE}`, you can show or hide specific content sections based on the user's group membership or privileges. This technique allows you to "tease" premium content to non-paying users or tailor the user experience based on their access level.

Question	What are match-key permissions and why would I use them?
Answer	Match-key permissions provide a more granular level of access control beyond the standard zone, page, and category permissions. They allow you to restrict access based on specific "match-keys", which are unique identifiers for different actions or content within Composr. For instance, you could use match-key permissions to prevent guests from submitting banners or to restrict access to the member directory for all but specific usergroups. You can also specify custom access denied errors for each match-key. A "match-key" is typically a page-link, such as `cms:cms_banners:add`.

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 are the different media types supported for banners?
Answer	The Composr banner system supports various media types: Images: Uploaded directly or via an image URL. Text: Textual banners, including support for "hot text" that dynamically displays banners based on keyword matches within the content. Frames: Banners embedded within frames using an iframe URL. Direct Code: Raw HTML or PHP code can be used to integrate banners from third-party banner networks or create custom banner implementations.

Question	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.

Question	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.

Question	Can I restrict who can see specific banners?
Answer	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.

Question	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.

Question	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.

Question	What should I do if an addon causes problems on my Composr website?
Answer	Composr's Safe Mode can help isolate addon-related problems. Enable Safe Mode: Use the safe mode link or the config editor (http://yourbaseurl/config_editor.php) to enable Safe Mode. Uninstall the problematic addon: Once in Safe Mode, navigate to the addon management section and uninstall the addon causing the issue. Disable Safe Mode: After resolving the problem, disable Safe Mode through the config editor.

Question	How can I manually edit my Composr database?
Answer	phpMyAdmin is a widely used web-based tool for managing MySQL databases. It allows you to: Browse tables: View and edit individual rows within database tables. Run SQL queries: Execute SQL commands directly for specific tasks. Repair corrupted tables: Access table repair functions. Refer to the "Manually editing your database with phpMyAdmin" tutorial for more detailed instructions.

Question	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.

Question	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.
