Resolved! Like you, simonco, I had a field not an email address. Changed it and now everything is ok.
Thanks simonco and buzztone
Hi simonco, I have the exact same problem as you describe in your initial post. I also do not have captcha.
Have you had any luck following buzztone’s advice?
I created a new form and it worked once, but then stopped working again.
Does this help anyone diagnose the issue? Any help much appreciated.
