I created a rather long form and once it was posted, though it viewed, it would not send. Moreover, the mechanism that required "required" fields to be filled in didn't work.
After a couple of hours, I found the culprit. I had select "website" field from the "Advanced Field" options, it's what prevented my forms from working. (I had tested this on 2 forms.) So, maybe there's a bug in this field opption?
Has anyone come across this problem? Is there a fix?
