I am getting no where with this???
Ok, I tried changing the form post as you requested and it does not work.
So to eliminate any other stuff that may be been on that page I used the Webassist CSS form builder to create a default contact page that postes to itself and then added the universal email to send me a simple email and it still does not work???
Here is the link to test and I have attached the code for this page:
If you submit the form something is missing that will not allow the page to reload. If I remove the universal email behavior it works fine. I have not changes any code. I started with a blank page and used all default Webassist software.
I also tried it with and without the port #.
