Question What does it mean to "outmode" a download?
Answer Outmoding means marking a download as superseded or replaced by a newer version. When editing the older download, you link it to the new one in the "outmode" field. This makes it clear to users that there is a newer version available. This is handy especially if you provide software.
Question What are the different ways to add downloads to my Composr site?
Answer Composr offers several methods for adding files to the download system:

  • Uploading via web form (when adding a download in the Content Management Zone): This is the simplest method, where you attach the file directly when defining the download details. However, it's not suitable for large files and can be affected by unreliable internet connections.
  • Uploading and referencing the URL: You can manually upload the file using FTP/SFTP/SCP and then provide the URL to the file in the 'Add download' form. While this is better for large files, it requires additional
 access, and the file isn't managed directly by Composr.
  • Batch adding from an FTP server: This allows staff to add multiple downloads from an FTP server in one go using FTP URLs. It's efficient for bulk uploads but requires separate addition of descriptions.
  • Batch adding from a directory: Similar to the FTP method, staff can add downloads from a web server directory accessible by URL.
  • File/media library (filedump): Webmasters can use any of the above methods to upload a file to uploads/filedump and then reference it in a download. This is especially handy if you are going to reference the file more than once on your site.
Question What is the Composr Setup Wizard and what does it do?
Answer The Setup Wizard is a guided process to help you configure essential settings for your Composr website after installation.

It can:
  • Generate a default theme and logo
  • Set initial site options
  • Remove predefined content and unnecessary addons
  • Place initial blocks on your pages

While convenient, be aware that re-running the Setup Wizard may overwrite existing settings and customizations if you already configured your site.
Question How can I change the structure of my Composr website's pages?
Answer You can delete and move pages using the Admin Zone > Structure > Sitemap editor. However, moving pages between zones might invalidate existing page-links unless specified using the _SEARCH zone in the link.

To avoid issues with existing links and search engine indexing, consider setting up redirects when moving pages. This can be done through Admin Zone > Structure > Redirects.

It is recommended not to move default Composr pages as it can complicate future upgrades.
Question What are Installation Options and how can I change them?
Answer Installation Options are low-level settings for Composr, such as database details and default language.

You can access the Installation Options editor through:

  • The script: http://yourbaseurl/config_editor.php
  • The Admin Zone: Admin Zone > Setup > Configuration > Installation Options

Remember that you'll need your maintenance password, specified during installation, to access and modify these options.
Question How do I open or close my Composr website to the public?
Answer By default, your Composr site is closed after installation. To open it to the public (or to close an opened site), go to Admin Zone > Setup > Configuration > Site options > Closed site and adjust the setting accordingly. You can also configure a closed site message.

While a closed site prevents public access, it's worth noting that users can still join a closed Conversr-powered site if they have access to the join module URL. However, they won't be able to log in unless they're assigned to a usergroup with "Access closed site" permissions. You can modify the join module's permissions to restrict access further.
Question What is the .htaccess file and how does it relate to Composr?
Answer The .htaccess file is a configuration file for the Apache web server. It allows you to define settings that apply to the directory where it's located and its subdirectories.

Composr can leverage .htaccess to enhance security and enable features like "URL Schemes." You can try renaming the provided recommended.htaccess file to .htaccess. This file includes recommended options that tighten security and ensure Composr has necessary PHP and Apache features activated.

Note that some web hosts might restrict the use of .htaccess files.

You should regularly review recommended.htaccess for changes between Composr updates.
Question How do Composr permissions work?
Answer Composr employs a multi-layered permission system with two main types: privileges and access permissions. The system grants users the best possible access based on the combination of their usergroups.

Privileges define broad permissions, such as accessing a closed site or content manipulation abilities based on impact level (low, medium, high). You can set privileges for usergroups via checkboxes, with the option to override them for specific pages or categories. Go to Admin Zone > Security > Global privileges.

Access permissions control what content users can view. These permissions are layered:

  • Zone access permissions
  • Page (or content entry) access permissions
  • Catalogue access permissions
  • Category access permissions

To configure access permissions, you can edit the specific resource or utilize the Permissions Tree Editor under Admin Zone > Security > Permissions Tree Editor.
Question How do I set up the system scheduler in Composr?
Answer The system scheduler is crucial for scheduled tasks like sending notifications, running backups, and processing reports. To set it up, you need to schedule a system-level task to run the data/cron_bridge.php file at least every 10 minutes. This links Composr's scheduler with your server's scheduler (like Cron on Linux).

Composr can often detect the correct command to use for your setup. You can check by visiting http://yourbaseurl/data/cron_bridge.php?query_mode=1, which should display the suggested Cron command. Note that you may need to replace the php command with the absolute path to PHP if you cannot use the php command directly.

If your hosting doesn't support Cron or scheduled tasks, you can enable scheduled tasks to run when visitors access your site. Navigate to Admin Zone > Setup > Configuration > Performance options and check "Web requests run scheduled tasks". Keep in mind that this method relies on visitor traffic and isn't as reliable as a dedicated scheduler.

Alternatively, consider using external services like EasyCron, setcronjob.com, or onlinecronjobs.com. These services allow you to schedule calls to the data/cron_bridge.php script by URL at specified intervals.
Question What are the different security levels in Composr's Setup Wizard and what do they affect?
Answer Composr offers five security levels in the Setup Wizard: Minimum, Low, Medium, High, and Ultra High. Each level sets various security configurations that you can later customize under Admin Zone > Setup > Configuration.

The security levels influence settings such as:

  • Content Security Policy
  • Session expiry time
  • Password reset process
  • Password expiry days
  • Minimum password length and strength
  • Login error secrecy
  • IP strictness for sessions
  • Cryptographic ratchet
  • CAPTCHA usage
  • Brute force threshold
  • Audio CAPTCHA
  • URL Monikers
  • .htaccess restrictions on maintenance scripts
  • Enquiry on new IP addresses

The higher the security level, the more stringent the security measures, with Ultra High offering the most robust protection but the most potential inconvenience to users.

Generally, you should use these settings depending on your site:
  • Minimum: Very bare-bones informational-only sites
  • Low: Sites which do not allow public registrations and do not use eCommerce but have content managed by different staff, and are not concerned with privacy or data
  • Medium: Sites with social features / public accounts but do not use eCommerce.
  • High: Sites which use eCommerce.
  • Ultra High: Sites containing very sensitive data, such as but not limited to cybersecurity sites, government departments, banks, healthcare, etc.

Question What payment gateways does Composr support?
Answer Composr supports PayPal, CCBill, and Authorize.Net for processing payments. While Composr could be extended to support other gateways, doing so may require professional development and customization.
Question What are the limitations for uploading large files?
Answer
  • 32-bit PHP build: Files larger than 2GB are not supported.
  • 64-bit PHP build: Files larger than 2GB are supported, but the file size will not be displayed.

For very large files, it's recommended to upload them manually and provide the URL instead of directly uploading them through the web form.
Question Can users search for specific downloads?
Answer Yes, the unified Composr search system allows users to find downloads based on keywords. This includes searching within download titles and descriptions, as well as within the content of certain file types like PDFs, text files, and even some binary formats (providing they are not too large in size).
Question Can I add images to my downloads?
Answer Yes, Composr automatically creates a gallery for each download (if the galleries addon is enabled). You can easily add images directly after creating the download or through the download-view screen. The download gallery is displayed within the download-view screen itself.
Question Are there security features to protect downloaded files?
Answer Yes, Composr includes security measures to protect downloads.
  • Protection from hackers: Uploaded files are stored with obscured filenames, preventing direct access and bypassing of the download system. Additionally, an anti-leech feature (when enabled) prevents direct download links from being shared on other websites (this is done by requiring a session ID which is validated against the person / device accessing it and only provided when Composr presents the download links to you on the site).
  • Basic security: Composr will not let anyone upload dangerous scripts (such as PHP files) which can be executed.
  • Rootkit detection: The rootkit detection tool under yourbaseurl/rootkit_detection.php can help scan files for shell scripts and backdoors. Composr's Health Check can also do this regularly. Note this only offers very basic detection and will not work for obfuscated backdoors (you should use antivirus to scan for those).

It is the responsibility of webmasters to run antivirus on their site to regularly scan files uploaded to it. Composr does not include antivirus software or virus scanning.
Question Where are download galleries located, and can I move them?
Answer By default, download galleries (to contain screenshots of a download) are placed under the root gallery. You can move them to a different gallery for better organization. Here's how:

  • Create a new container gallery (e.g., with codename "downloads").
  • Change the "Create download galleries under" configuration option to your new gallery's codename.
  • Use Commandr to move existing galleries to the new location.
Question Can I sell downloads on my Composr site?
Answer Yes, the download system integrates with the points system, allowing you to charge for downloads. This is particularly useful for communities where members create and share content, like game modifications. You can set prices for downloads and creators earn points when users purchase them. Additionally, you can create a subscription-based system by requiring points for downloads, which users can purchase via methods like PayPal.
