I Eric,
I have did some tests.
I have uploaded the form and "webassit" folder on Linux server, the form has worked fine.
I have uploaded the form and "webassit" folder on Win server (PHP and MySQL installed), the form didn't work.
In any case the WAUE v3 worked fine. If the problem is not located, how can I go back to v3?
(I remember you: I have also tried uninstalling v 4.01 and to install 3.07, but when I open UE 307 behaviour, I get Javascript error. So I had to install 401 again.)
Thanks
Alex
