We've done testing with earlier versions of 3.9, but haven't tested the full release yet.
As to your issue, can you explain things more as to what is happening? Is it the privacy options for GPDR that are showing at the bottom of the page or is it all forms? Can the forms be seen at all or are they too far off the page?
Any details you can give us on how you have things setup or if you can post or Private Message us a URL to see the issue on along with what to do to trigger it, that would help. You can PM us by clicking the mail icon next to my name on the left.
Thanks,
Alex
