The code is generated by Muse, and is miles long. Also there is no send.php, there's a form_check.php, a form_process.php and a form_throttle.php.
I have done some further testing, and this is how my problem looks now:
I uploaded my page about a month ago, bought a domain name that I linked to the host, and everything was working fine. Then I tried to test the form a couple of days ago, and it doesn't work. Nothing has changed on my end, and I cannot find anything wrong.
My form is sending to two email-addresses, both to my gmail directly and to my domain. The address that is directed at the domain is then forwarded to my gmail. When I tested it a month ago, the last one was working, but not the one set up directly to my gmail.
The strange thing is that when I upload my page to business catalyst (adobe server), it works perfectly and I actually get two emails. I get the one that is sent directly to my gmail, but I also get the one that is sent to my domain, and then forwarded to my gmail. So the forwarding obviously works.
Does anybody know where the problem might be? I have no idea even where to look...
