I know this forum isn't checked often, but the client-of-a-client doesn't have Pro, and at this point I am more or less doing this as a favor. Client changed web hosts. Forms worked fine before, now they don't. Email is hosted at 3rd party. If I change the "To" email address from "firstname.lastname@example.org" to "email@example.com" the web forms come through, but if I use a domain-related email, the forms do not come through.
Host says the issue is with plugin, but all my research indicates an issue with the host. Also, when forms are submitted, a PHP warning appears at the top: Warning: extract() expects parameter 1 to be array, null given in /hsphere/local/home/a915312/mydomain.com/wp-includes/pluggable.php on line 216
I figured that indicated a host setting issue, but host says it is a plugin issue. Can anyone provide assistance? Thanks!
