Mi13 Cache is a simple and effective plugin for caching WordPress pages. It saves HTML pages as files and serves them on subsequent requests, significantly speeding up site loading. Key features: Line-by-line caching of HTML pages. Flexible settings: select which page types to cache. Automatic cache clearing when content is updated. Cache status displayed as an HTML comment at the beginning of the file. Cache statistics: file size and number of files. Security: access permission checks and filtering of system pages. Compatibility with custom post types. Usage After activation: Go to Settings → Mi13 Cache. Configure the settings: Select page types to cache (home page, posts, pages, categories, archives, custom types). Set the cache lifetime (in seconds; default is 86 400 s / 24 hours). Clear the cache manually using the Clear Cache button (if needed). Save the settings. You can check the cache status in the page source code: Open the page source code (press Ctrl+U or right-click → “View Page Source”). Look for a comment at the very beginning of the HTML file, like this: Settings Page types — select which content types to cache. Cache lifetime — the interval in seconds after which the cache expires. Clear cache — a button to manually clear all cached files. HTML comment format The plugin adds an HTML comment with information to the beginning of each cached file: Limitations Caching does not apply to: authenticated users; the admin panel; 404 pages; search pages (?s=...); RSS feeds (/feed/); AJAX requests; POST requests; URLs with GET parameters (except paged for pagination). Troubleshooting Issue: the cache is not created. Solution: make sure that: define('WP_CACHE', true) is present in wp-config.php; WordPress has write permissions for /wp-content/cache/mi13-cache/. Issue: pages do not update after editing. Solution: manually clear the cache on the settings page. Issue: access permission error when clearing the cache. Solution: check file permissions in the cache directory. Security Permission check (manage_options) before clearing the cache. Caching disabled for authenticated users. Exclusion of system pages (404, search, feed, etc.). Use of the secure WordPress API for file system operations. Directory structure Cached files are saved in: /wp-content/cache/mi13-cache/ Each file has the .html extension and a name corresponding to the page URL.
