    remove_all_filters( 'the_content' );

    This example will remove all hooks from the_content function, for any plugin or theme.
    But if you only want to remove a particular set of hooks at a particular priority, you can use a priority, 10 being the default used for most filters:

    remove_all_filters( 'wp_delete_file', 10 );

    Since class-derived filters can be tricky to remove, if they use a non-default priority (take 15 for example), you could do this instead:

    remove_all_filters( 'wp_delete_file', 15 );
  2. Skip to note 2 content


    remove_all_filters('the_content', 'plugin_filters');

    This example will remove all of the plugins hooks from the_content function.
