502 error when manually clearing the cache

If you see a 502 error from Cloudflare when clearing the WP Rocket cache, please check if you are also using the Query Monitor plugin. 

In some cases, this combination can lead to the 502 error. 

If you are not actively using Query Monitor, you should deactivate it. 

Or, you can add this code snippet which will resolve it: 

add_action( 'before_rocket_clean_domain', function() {
    do_action( 'qm/cease' );
} );
