Sorry,
this doesn’t solve the problem.
Your instruction was clear, and I ckecked it again and again, at least, built the form new, but there is no change by the problem.
Is it possible, to get an older Version before all the last updates?
If we don’t find a solution, we will have to replace the tool on our Divi pages.
That, in turn, would be a great pity, since so far it has done exactly what it was supposed to.
I hope you can help us.
