I have 3 different forms running on my site and since a server migration they have stopped working correctly. One of the forms works perfectly the other two say that the form has been sent successfully but it never arrives in my inbox. I can mimic the settings exactly but it does not work. Only one contact form ID successfully sends emails.
I also noticed (I dont know if its linked) but I cannot duplicate a form. When I click the button it just adds _copy to the existing form (same ID) and no additional form is created.
I have checked the usual problems i.e. spam that is not the issue.
Any help would be appreciated!
