We've got a form which went live this morning, which is getting loads of entries and it's critical that it works correctly. The form is at http://www.moving-4-ward.com/register/register-for-the-industry-forum/
The form seems to have issues with certain email addresses. When I try and sign up with the following information, the form returns error 324 and there is no response from the server.
Name: Robert Nagel
Company: SNC Lavalin Transportation USA
Address: 13901 Sutton Park Drive South
Jacksonville, Florida 32224
The entry is recorded in Gravity Forms, however, the email address is not forwarded to iContact (I'm using the iContact plugin: http://wordpress.org/extend/plugins/gravity-forms-icontact/ - I tried removing the feed from this form, but it didn't affect it). If I change the email address however, it goes through OK.
It is critical that these forms are up and running ASAP. Any ideas on what the issue might be?
