A couple of months ago I set up a contact form for a client's website at http://davidmorrisprojects.com and it worked but two months on it no longer appears to be working. When a message is sent, the page refreshes with the thank you message, but no messages get through to the designated Sent To email address.
The site is using Wordpress 3.4.1 and the Gravity Forms plugin is up to date. The contact form has been embedded using the Gravity Forms sidebar widget. I'm wondering if this could be the source of the problem? The reason is that I've gone back and tested my (Gravity) contact forms that I use on some other sites, where the form is embedded into the page with a shortcode, and they're all working fine.
