Yes, indeed I have Black Studio TinyMCE Widget and TinyMCE Advanced.
I updated the newest version and unfortunately the problem is still there.
I was testing yesterday form builder plugins but none of them is ideal.. so I haven’t decided yet which one to use and I will gladly check out PlanSo as well.
