PHP-Info provides a comprehensive overview of your PHP configuration. You can access it within Composr by navigating to Admin Zone > Tools > PHP-Info / Server Checks.
This page also provides additional useful server information.
What is the purpose of the Health Check feature in Composr?
Answer
The Health Check feature in Composr proactively identifies potential issues that may affect your website's performance, security, and overall health. It performs various checks and alerts you to problems like:
Broken links and forms
Security vulnerabilities
Outdated software versions
Server performance issues
Email configuration problems
The Health Check can be run manually or scheduled to run automatically and send e-mail notifications of results.
How can I use Content Delivery Networks (CDNs) to enhance my website?
Answer
CDNs improve website performance by serving content from geographically distributed servers, reducing latency and server load. You can leverage CDNs for your Composr website by:
Configuring the CDN option in Composr with a comma-separated list of CDN domain names.
Ensuring your files are mirrored on the CDN servers.
Utilizing the CDN_FILTER directive and symbol to control what content is served via CDN.
What is rate limiting and how can I enable it in Composr?
Answer
Rate limiting prevents server overload by restricting the number of requests allowed from a single IP address within a specific timeframe. To enable Composr's built-in rate limiting, add the following to your _config.php file:
Static caching drastically improves performance by serving pre-generated pages to bots and guests. This works because these users typically don't require dynamic content. To enable it:
Go to the Installation Options editor (yourbaseurl/config_editor.php). You will need your maintenance password.
Activate the static cache option.
Composr intelligently determines what to cache, and you can further control this via options within the Installation Options. Be aware that enabling static caching may disable eCommerce features for guests unless specifically configured.
If you're having issues with notifications, here are some troubleshooting steps:
Check Email Logs: View the email log (Admin Zone > Audit > E-mail queue/log) to see what notifications have been sent.
Use the SU Feature: Impersonate a member using the SU feature (described in the "Testing access and privileges" tutorial) to view their notification settings and confirm they are set up correctly.
Enable Carbon-copy Email: Configure a "Carbon-copy e-mail address" in the configuration settings to receive copies of all outgoing emails, including notifications. This helps you monitor email delivery.
Verify System Scheduler: Ensure the system scheduler is configured correctly if members are not receiving digest emails.
Check Digest Settings: Confirm that "Enable digest notifications" is enabled in the Messages configuration settings.
Review "Safety listing limit": If a notification has too many categories, members might not see the full selection tree. Adjust the "Safety listing limit" in the configuration settings if necessary.
Can I control which notifications members receive?
Answer
Yes, you can control notification settings through two mechanisms:
Notification Defaults: You can set default notification preferences for all members. You can enable or disable specific notifications and choose the delivery method (Admin Zone > Setup > Notification defaults).
Notification Lock-down: You can force members to receive or prevent them from receiving certain notifications (Admin Zone > Setup > Notification lock-down). This allows you to enforce specific notification policies and manage email volume.
What notification options are available to members?
Answer
Members can choose from a wide range of notifications, including:
Content Updates: Notifications for new or updated content, such as news articles, forum posts, and gallery images.
Private Messages: Alerts for new private messages received.
Friend Requests: Notifications for new friend requests.
Administrative Actions: Alerts for actions taken by site administrators, such as account approvals or content moderation decisions.
Members can choose to receive notifications via:
Email: Notifications sent directly to their email address.
Digest Email: Combined summaries of activity sent in batched emails. This requires the system scheduler and the digest e-mails configuration option to be enabled.
Private Topics: Notifications delivered as private forum topics.
SMS: Notifications sent as text messages (requires configuration and incurs costs).
Web Notifications: Real-time alerts displayed within the Composr interface.
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.
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.
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.
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.
What is the difference between natural and boolean searching?
Answer
Natural search is a more relaxed approach where you type in your search terms and Composr tries to find the most relevant results, even if they don't contain all the words. It's like a Google search.
Boolean search requires more precision and uses operators like "+", "-", and quotation marks to define exactly what you're looking for. For example, searching for "+car -maintenance" will only return results that contain the word "car" but not "maintenance".
There are a few ways to search your Composr website:
Using the search bar in the header: This is the simplest way to search. Just type your search term in the box and click the search button.
Using the 'Search' module: This module offers more detailed search options. You can access it via the 'site:search' page-link (usually under About > Search in the default menu).
From the Forum: Click the 'Search' button on the forum or use the contextual search box on the forum member bar. This will search within your current forum or topic.
For questions with predefined answers, you can mark correct answers by adding [*] after the answer. If no answer is marked correct, the question will require manual marking. You can also use the [UNMARKED] tag after a question to exclude it from scoring.
Quiz questions are inputted in blocks, separated by blank lines. The first line is the question, followed by potential answers on subsequent lines. Different question types are indicated by tags after the question, such as [MULTIPLECHOICE], [MULTIMULTIPLE], [LONG], [SHORT], and [SHORT_STRICT].
