Anti-Cache Kit for WordPress

Detects nginx and Caddy and skips rules that would not apply there, offering an equivalent nginx snippet to copy instead

Cleanly removes only its own rules on deactivation, leaving the rest of .htaccess untouched

Debug mode activation

Enables WP_DEBUG, WP_DEBUG_LOG, and SCRIPT_DEBUG (errors go to wp-content/debug.log)

Sets WP_DEBUG_DISPLAY to false so errors are logged, not shown on screen

Disables WordPress cache (WP_CACHE = false)

Comments out conflicting definitions with visible markers instead of deleting them

Wraps its own definitions in markers and reverts them on deactivation, preserving any WP_DEBUG, WP_CACHE or SCRIPT_DEBUG you had set yourself

Modifies wp-config.php with the WordPress Filesystem API, validates the result before writing, and never keeps a copy of your credentials on disk

Maintenance mode

Optional status page for non-logged visitors

Quick toggle from admin bar

Customizable via filter hook

Self-contained output with aggressive cache prevention headers (503, no-store, Surrogate-Control)

Safety and environment

Detects production sites with wp_get_environment_type() and shows a dismissible warning, plus a red dot in the admin bar

Status panel reflects the real state: debug constants, server rules, detected environment, and whether wp-config.php is writable

Removes its options and any leftover backup directory from older versions on uninstall
