In any case, it’s not working because is_required()executes first than your function. Solutions: 1) Remove the * in the backend OR 2) Change the priority // From 20 … Read more
The question is: Is it possible to hook with apply_filters or add_filters on their function, manipulate it adding HTML to that page? apply_filters and add_filter() do two separate things. apply_filters allows a value to be filtered by add_filter().
