Question What is the purpose of "confirmed" and "non-confirmed" sessions?
Answer Composr distinguishes between confirmed and non-confirmed sessions for added security:
  • Confirmed: When you actively log in with your credentials.
  • Non-confirmed: When you return to the site and are automatically logged in via cookies.

You can configure zones to require confirmed sessions, preventing access from cookie-based logins alone. The Admin Zone uses this by default.
Question How can I enhance the security of my Composr installation on shared hosting?
Answer Shared hosting environments can be inherently less secure. Here are some tips:
  • Choose a Secure Host: Opt for hosts that offer suEXEC and open_basedir for better account isolation.
  • Test Security: Verify the host's security measures with the provided filesystem_browser.php script.
  • Restrict _config.php: Remove world-writable permissions from _config.php after installation.
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.
  • Secure Computers: Keep your own devices patched and secure.
  • Maintenance Password: Remove the maintenance password from _config.php when not in use.

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 contribute to translating Composr?
Answer You can contribute to Composr's internationalization by:
  • Joining the translation team on Transifex: Translate language strings collaboratively with other volunteers.
  • Becoming a language maintainer: Take responsibility for the translation and support of Composr in your native language.
  • Reporting translation issues: If you encounter unclear, incorrect, or duplicated language strings, file bug reports.
  • Providing feedback and suggestions: Share your thoughts on improving the translation process through feature suggestions.
Your contributions are valuable and help make Composr accessible to a wider audience.
Question What is Transifex, and how does it help with translation?
Answer Transifex is a collaborative online platform used by the Composr community for translation. Its benefits include:
  • Centralized translation efforts: Multiple translators can work on the same project.
  • Improved translation quality: The platform facilitates consistency and accuracy.
  • Simplified language pack creation: You can generate downloadable language pack addons directly from Transifex.
We encourage using Transifex for translation to foster collaboration and maintain high-quality translations.
Question Can I translate images with text on them?
Answer Yes, you can translate images containing text. In the themes/default/images/ directory, you'll find an EN folder containing images with English text.
  • Copy the EN folder: Create a new folder with the ISO code of your target language (e.g., FR for French).
  • Replace the images: Replace the English images with translated versions.
  • Ensure correct image paths: Update any references to these images in your templates or content to point to the translated versions.
Question How do I translate the content on my Composr website?
Answer Once you've installed a new language pack, you can translate existing content by:
  • Editing the content directly: Go to the specific content item (page, news post, etc.) and edit it in the new language.
  • Using the language editor: Access the language editor from Admin Zone > Style > Translate/rephrase Composr to modify language strings used on specific pages.
Note that some elements like forum names are not designed to be translated directly. Instead, you should create separate forums for each language.
Question How do I change the language of my Composr website?
Answer Composr comes with English as the default language. To change to a different language:
  • Download the language pack: You can download language packs from the Composr website.
  • Install the language pack: Upload the downloaded language pack addon through Admin Zone > Structure > Addons > Import non-bundled addon(s).
  • Change the default language: Go to http://yourbaseurl/config_editor.php and set the desired language.
  • Update your profile: If you had a previous language set in your profile, update it to the new language.

You can test a language without changing settings by appending &keep_lang=XX to the URL, where XX is the language code (e.g., FR for French).
Question What should I do after successfully importing data into Composr?
Answer After importing, if all files like avatars, photos, and attachments have been copied to Composr's directories, you can remove the imported product's directory. However, it's advisable to keep the directory, database, and import session for a few weeks in case any data was not correctly imported and needs further attention. Importing is a complex process, so keeping backups and sources for a while is a good practice.
Question Where can I get help with the import process?
Answer The Composr documentation provides extensive information. Additionally, you can seek assistance from experienced Composr developers, including the Composr team if your project allows for professional support.
Question Can I switch from a third-party forum to Conversr (Composr's built-in forum)?
Answer Yes, if an importer exists for your current forum software, you can switch to Conversr during the import process. Composr will handle the forum driver switch and remap user IDs, but it's recommended to double-check permissions afterward.
Question How does the HTML website importer work?
Answer The HTML website importer is an advanced tool for migrating static HTML websites to Composr. It analyzes the HTML structure to create zones, Comcode pages, and a basic template. It also attempts to fix links and file paths for Composr compatibility.
Question What is a Composr import session?
Answer Import sessions track the progress and ID remapping for each import, allowing you to merge multiple sites or resume interrupted imports. This is particularly useful when merging multiple Composr sites into one.
