I’m having a similar issue. I am using CFDB with Contact Form 7. As soon as I activated CFBD I’m not receiving the emails from Contact Form 7. When the online form is completed, there is a nice green ‘success’ message. The data is captured successfully by CFDB. But the email from Contact Form 7 never appears.
As soon as I deactivate CFDB plugin, the issue is resolved. Is there a plugin conflict perhaps?
Many thanks
James
