Question How does Composr protect against Cross-Site Scripting (XSS) attacks?
Answer Composr utilizes multiple layers of defense against XSS attacks:
  • HTML Filtering: Configurable levels of filtering prevent malicious script injection.
  • Content Security Policy (CSP): Restricts the sources from which scripts and other resources can be loaded.
  • Input Sanitization: Data is sanitized before being processed to prevent malicious code execution.
  • Output Encoding: Data displayed to users is properly encoded to prevent interpretation as active code.
Question What are the different types of security alerts in Composr?
Answer Composr has a variety of hack-attack codenames that trigger security alerts and logging. Some common examples include:
  • DODGY_GET_HACK: Suspicious URLs with potentially harmful characters.
  • EVIL_POSTED_FORM_HACK: Possible CSRF attempts via malicious form submissions.
  • SCRIPT_UPLOAD_HACK: Attempts to upload PHP scripts, potentially malicious.
  • DOWNLOAD_PRIVATE_URL_HACK/TRY_TO_DOWNLOAD_SCRIPT: Attempts to download sensitive files.
  • BRUTEFORCE_LOGIN_HACK: Repeated failed login attempts.
  • SQL_INJECTION_HACK: Attempts to exploit SQL queries for data extraction.

You can customize alert handling for each type in data_custom/xml_config/advanced_banning.xml (Admin Zone > Security > Configure advanced banning).
Question What are some tips for secure website maintenance?
Answer
  • Avoid FTP: Use secure alternatives like SFTP or SSH for file transfer.
  • Secure Email: Enable SSL for IMAP and POP3 email protocols.
  • Strong Passwords: Use unique and complex passwords for different services.

Question Why are my searches slow, and how can I improve search speed?
Answer Slow searches can occur when dealing with large amounts of content. Here are some workarounds and solutions:
  • MySQL timeout setting: For MySQL 5.7+, set a query timeout to prevent searches from locking up your database. Composr automatically sets this, but you can configure it manually if needed.
  • Use InnoDB tables: Switching to InnoDB tables in MySQL can prevent slow queries from affecting other users on your website. Note that InnoDB is not officially supported by Composr yet.
  • Enable the fast custom index: As mentioned earlier, the fast custom index is optimized for handling large datasets and filtered searches, potentially leading to significant speed improvements.
Question How does the search engine handle different languages?
Answer Composr's fast custom index supports multiple languages. Content is indexed based on its translated version, ensuring that you get relevant results even when searching in a different language.
Question What are quoted phrases and how do they work?
Answer Quoted phrases allow you to search for an exact sequence of words. For example, searching for "red apple" will only return results containing that exact phrase. Keep in mind that enabling quoted phrases can increase disk space usage.
Question How do stop words affect search results?
Answer Stop words are common words (like "the", "a", "is") that are ignored by the search engine because they add noise and don't contribute to the meaning of the search query. You can customize the list of stop words for the fast custom index. See the search tutorial for more information.
Question How can I improve my search results?
Answer Here are some tips for improving search results:
  • Use specific keywords: The more specific your keywords, the better your results.
  • Use boolean operators: Use "+", "-", and quotation marks to refine your search.
  • Optimize content titles and meta keywords: These fields are given priority during search, so make sure they accurately reflect your content.
  • Consider enabling the fast custom index: Especially beneficial for large websites or frequent filtered searches.
Question What is the fast custom index and why should I use it?
Answer The fast custom index is Composr's own search engine, designed to be faster and more efficient than MySQL full-text search, especially for large websites and filtered searches.

Benefits of the fast custom index:
  • Faster filtered searches: Significantly improves search speed when you add filters like category or author.
  • Configurable stop words: Control which common words are ignored during search.
  • Better stemming: More accurately recognizes variations of words (e.g., "like" and "liking").
  • Multilingual support: Indexes content based on different language translations.

Downsides of the fast custom index:
  • Slight lag in indexing new content: New content takes a short time to be indexed.
  • Less accurate ranking: Ranking is based on the most obscure keyword, not a blend of all keywords.
  • Cannot perform blank searches: You must enter at least one keyword.

Question How can members edit their profiles and account settings?
Answer Members can edit their profiles and account settings through the "Edit" tab on their profile page. They can change their password, update personal information, manage their avatar and signature, and adjust their privacy settings. Administrators have access to additional options for managing member accounts.
Question What is the difference between member terms?
Answer
  • Visitor: Any one or device who visits the site but is not necessarily identified
  • User: Any visitor who can be identified (e.g. has a session ID or tracked IP address)
  • Guest: A user who is not logged in (in Conversr, they all share a special "Guest" ID / account)
  • Member: A user who is logged in with a registered account on the website (they have a username and a member ID)
  • Author: Specific to the authors addon, a profile of an entity (could be a member, individual, or even a company) who makes content for the site
  • Subscriber: A user who receives newsletters from the site (they do not necessarily have to be a member)
  • Submitter: A user who submitted content (usually a member, but could be a guest if the site is very open to submissions)
  • Staff: A member who moderates any significant portion of the website
  • Super-moderator: A staff member with global moderation capabilities
    • Moderator: Same as super-moderator but does not have those capabilities globally; they may only be able to moderate certain sections or content
  • Super-administrator: A staff member with literally undeniable access to everything on the site
    • Administrator: Same as super-administrator but they might not have access to the most elevated of privileges such as accessing maintenance scripts

It's important to understand these distinctions to properly manage permissions, track user activity, and personalize the website experience.
Question What are Welcome Emails and how do they work?
Answer Welcome Emails are a series of automated emails sent to new members on a predefined schedule. They can be used to introduce the website's features, encourage engagement, and provide helpful information. Website administrators can customize the content and schedule of these emails.
Question How can I enhance or enforce the security of member passwords?
Answer Composr offers several features to improve password security:

  • Password Strength Setting: Administrators can set a minimum password strength requirement, forcing members to choose stronger passwords. Password strengths are calculated on a scale of 1-10 using algorithms that take into account letters (including case), numbers, symbols, repeat characters, use of dictionary words, and use of usernames / dates of birth / e-mail addresses.
  • Forced Password Resets: Administrators can force specific members or all members to change their passwords upon next login, enhancing security in case of potential breaches.
  • Expiring passwords: Administrators can require members to change their password after so many days.
  • Encrypted CPFs: If the server has the OpenSSL PHP extension installed, specific CPFs (such as ones containing other passwords) can be encrypted to protect sensitive member data in case of a server compromise.
Question Can I import or export member data?
Answer Yes, Composr allows you to import and export member data using CSV spreadsheet files. This is useful for transferring member information between different systems, performing bulk updates, or creating backups. The export feature provides various filtering options, and the import feature supports adding new members and updating existing ones.

Go to Admin Zone > Security > Members > Export members.
Question What are usergroups and how do they work?
Answer Usergroups are a way to categorize members and assign them specific permissions and privileges. Each member can belong to one or more usergroups, and the permissions granted by those usergroups determine what actions they can perform on the website. Website administrators can create and manage usergroups, define their permissions, and assign members to them. They can also assign leaders who then have permission to manage the members of that specific usergroup.
Question What are Custom Profile Fields (CPFs) and how are they used?
Answer CPFs allow website administrators to collect additional information from members beyond the basic profile fields. These fields can be customized to fit the specific needs of the website, such as collecting job roles, hobbies, or interests. CPFs can be used to:
  • Enforce specific requirements for membership (e.g., job role in a company forum).
  • Categorize members based on their interests or affiliations (e.g., football players in a school forum).
  • Display additional information on member profiles and forum posts.
Question How do new members join a Conversr website?
Answer Members can join your Composr site in a few ways:
  • Regular Registration: Users can click on "join" links, agree to your rules, and fill out a registration form. They will then receive an activation email to confirm their email address (if enabled).
  • Invites: You can restrict joining to invite-only. Existing members can send invites, and only those who receive an invite can register.
  • Manual Addition: Administrators can manually create member accounts through the Admin Zone. This is useful for pre-joining members or handling issues with the regular registration process.
  • Other Methods: Composr also supports automatic member joining through LDAP and HTTP authentication.
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.
