What does this plugin do?

This plugin generates static html files from your dynamic WordPress blog. After a html file is generated your webserver will serve that file instead of processing the comparatively heavier and more expensive WordPress PHP scripts.

How does the plugin serve cached files?

The plugin serves cached files in 3 ways (ranked by speed):nn1. Expert. The fastest method is by using Apache mod_rewrite (or whatever similar module your web server supports) to serve “supercached” static html files.n2. Simple. Supercached static files can be served by PHP and this is the recommended way of using the plugin.n3. WP-Cache caching. This is mainly used to cache pages for known users, URLs with parameters and feeds.

What are the recommended settings for the plugin?

The recommended settings are:nn1. Simple caching.n2. Compress pages.n3. Don't cache pages for known users.n4. Cache rebuild.n5. CDN support.n6. Extra homepage checks.

What is garbage collection?

Garbage collection is the act of cleaning up cache files that are out of date and stale. It is recommended to set the expiry time to 1800 seconds.

How can I troubleshoot issues with the plugin?

If things don't work when you installed the plugin, you can check the following:nn- Is wp-content writable by the web server?n- Is there a wp-content/wp-cache-config.php file?n- Is there a wp-content/advanced-cache.php file?n- Is the constant WP_CACHE defined in wp-config.php?n- Are there directories and files in wp-content/cache/supercache/?n- Are there any error messages in the php error_log?n- Are there any issues with file permissions or file locking?n- Is the cache directory on a local disk?n- Is wp-cron.php accessible?n- Are the required Apache modules (mod_mime, mod_headers, mod_expires) enabled?n- Is the path to wp-cache-phase1.php correct in wp-content/advanced-cache.php?n- Are the mod_rewrite rules in the .htaccess file correct?n- Are there issues with compression or PHP error messages?n- Is APC causing issues?n- Have you regenerated the permalinks after uninstalling the plugin?n- Is your wp-config.php file correct?n- Have you checked the encoding settings?n- Have you checked the scheduled jobs with Cron View?n- Is the constant WPCACHEHOME set correctly?n- Are there issues with semaphores or file locking?n- Is the variable $htaccess_path set correctly?

Used to be good, now it is not

Updated 2024 After a lot of turbulances all these years, now it seems to be much better at last. Preload also works as expected :). It took several years for that :) Jetpack should not be promoted in the WP Supercache plugin. Jetpack is Not good at all.
