Frequently Asked Questions

Common questions about Prime Cache – Page Cache & Core Web Vitals (Zero Config)

WordPress 5.8+, PHP 7.4+. For WebP conversion, the GD or Imagick PHP extension is required.
No. Running multiple caching plugins causes conflicts. Prime Cache automatically detects and warns about 14 known caching plugins. Deactivate other caching plugins before using Prime Cache.
Yes. Page caching, file optimization, media optimization, and all PHP-based features work on any server. The .htaccess optimization feature is Apache-specific but can be disabled on Nginx.
Yes. WooCommerce cart, checkout, and account pages are automatically excluded from caching. Additional WooCommerce optimizations include disabling scripts on non-WC pages and disabling cart fragments AJAX.
Multiple ways: Admin bar menu (10+ options), Dashboard quick actions, WP-CLI commands (wp prime-cache flush), or automatic purge triggers.
Yes. Edit the post/page and check "Disable cache for this page" in the Prime Cache metabox in the sidebar.
The .htaccess fast-path serves cached pages without loading PHP for maximum speed. It requires: lowercase Host header, no query string (unless cache_query_strings is disabled), no Vary Cookies, ASCII-safe URL paths, and GET requests only. Requests that don't match these conditions are served via the PHP drop-in, which is still very fast but not zero-PHP.
Page caching is not supported on multisite installations. Other features (file optimization, lazy load, image optimization, etc.) work normally on multisite.
On upload (if auto-convert is enabled), JPG/PNG images are converted to WebP. All thumbnail sizes are also converted. WebP is served to supporting browsers via .htaccess rewrite rules, picture tags, or URL rewriting.
Start with page caching and basic file optimization. Test your site after each change. JavaScript defer and delay may affect some themes or plugins — test thoroughly.
