What are cleanup tools in Composr and how do I use them?
Answer
Cleanup tools assist with website maintenance by deleting unnecessary data and optimizing database tables. They are divided into "De-cachers" and "Optimizers". You can access them through:
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Outdated software versions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 other approaches exist for mobile integration with Composr?
Answer
Other approaches, in various stages of development, include:
Tapatalk: A third-party forum app with an official Composr addon, offering a high-quality "out-of-the-box" Composr app experience.
Further Composr Mobile SDK development: Plans and issues relating to the SDK's evolution can be found on the Composr tracker, driven by commercial projects and feature sponsorship.
How does authentication work with the server-side API?
Answer
Authentication is handled automatically using cookies, similar to regular website requests. If cookies are not feasible, the response parameters device_auth_member_id_cn/device_auth_pass_hashed_cn/device_auth_member_id_vl/device_auth_pass_hashed_vl from the login endpoint can be resent as POST parameters in subsequent requests.
How do I access the server-side API for my mobile app?
Answer
The server-side API can be accessed via HTTP calls to http://yourbaseurl/data/endpoint.php. Results are returned in JSON format. The API utilizes endpoints with a 'hook' name and a 'hook type' categorization. Both REST-style and GET-parameter style requests are supported, with the latter recommended for simplicity.
What is the purpose of the Composr Mobile SDK Toolkit?
Answer
The Toolkit, part of the composr_mobile_sdk addon, aids in mirroring Composr website resources into a mobile app. It includes tools for generating iOS/Android string resources from language files and exporting theme images in a directory structure suitable for iOS/Android app image assets.
To connect to a Composr site, you will need to install the composr_mobile_sdk addon, which is not bundled. This addon provides scripting to generate app assets from the Composr site.
Composr Mobile SDK (CMS SDK) is a toolkit designed for experienced iOS and Android developers to build mobile apps that integrate with a Composr-powered website. It offers both Composr-specific integrations and a collection of standalone utilities for building apps, providing a common base between iOS and Android akin to the PHP and Composr APIs, enabling easier code porting while maintaining a native experience.
