Heads up! Manual code edit is required before use!


To install the plugin please follow these steps:

  1. Download the helper plugin ZIP file.
  2. Customize the plugin's code:
    Edit line 32, change /product by a portion of the URLs where you'd like to disable RUCSS. All URLs that contain this string will be excluded.
  3. To exclude multiple groups of URLs, you can duplicate line 32 as many times as needed. Each if condition should be followed by the || operator, except the last one. There is an example commented and ready to use on lines 36/47:
        if ( 
            strpos( $url, '/product' ) !== false    || 
            strpos( $url, '/tag' ) !== false        || 
            strpos( $url, '/category' ) !== false   || 
            strpos( $url, '/size' ) !== false 
            ) {
                add_filter( 'pre_get_rocket_option_remove_unused_css', '__return_zero' );
