Question What is the Composr Member System?
Answer The Composr Member System is the system used by the Conversr forum software to manage user accounts and information. This includes usernames, passwords, profile information, and usergroups. It also handles user registration, login, and account management. For websites not using Conversr, the member system of the third-party forum software would be used.
Question Can I Use Composr Galleries to Publish Podcasts?
Answer Yes, Composr supports creating podcasts from galleries. The podcast URL follows this format: http://yourbaseurl/backend.php?mode=galleries&select=galleryname&type=rss&itunes=1. Replace yourbaseurl and galleryname accordingly. This URL can be used to subscribe to the podcast in iTunes or other podcast applications.
Question How Do Gallery Slide-shows Work?
Answer When viewing an image or video in a gallery, visitors can initiate a slide-show that automatically cycles through subsequent entries. The slide-show can be paused with a click or keypress. The default slide-show speed can be adjusted by modifying the GALLERY_ENTRY_SCREEN.tpl template.
Question What are Watermarks and How Do They Work?
Answer Watermarks are semi-transparent images overlaid on gallery images to mark their origin or deter unauthorized use. When you add or edit a gallery, you can choose to apply watermarks to the corners of images. Watermarking applies permanently to the uploaded image. Composr uses a reverse tree structure for watermarks: if a sub-gallery doesn't have a watermark defined, it inherits the watermark from its parent gallery.
Question Can Members Create Their Own Personal Galleries?
Answer Yes, members with the "have personal galleries" permission can create their own galleries. These personal galleries are displayed under designated "Personal category container" galleries. They also show up in a tab on the member's profile. Members can only add content to their own galleries unless they have the "Submit to categories belonging to other members" permission.
Question What are Rep-Images and How Do I Set Them?
Answer Rep-images, short for "representative images," are thumbnails that represent a gallery when it's displayed within a list of galleries. They offer a visual preview of the gallery's contents. You can set a rep-image when adding or editing a gallery, or when adding an image to a gallery.
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 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.
