Hello,
I appreciate your quick response. We have done some more troubleshooting on our end and we are still unable to get the plugin to work.
The main query on the category archive pages is clean and unmodified.
The only option we have under What to filter is Posts list <<Products>> Main Query.
The filter is setup using two ACF custom fields meta keys.
Does the free version filter work with ACF custom field meta keys? It was working up until recently.
