Hi

After Update to 4.1.0 the contact form "ask a question" is not working anymore.

I can fill in all fields and hit the submit button. But the form does not get submitted. Just the spinner is shown all the time.

How to solve this?

Thanks!

Regards

Hi

I did install it but the problem is not solved, still the same.

What now?

Thanks.

Hi

Thanks a lot for your help!
