I upgraded to WordPress 3.4.2, and since then, Formidible (Version 1.06.05) is not sending out notification emails. I know that both WordPress and other plugins are still sending out email. I just created a new user, and received the email notification, and WordFence is also sending out email.
Can you give me some guidence / help on where to look to fix this problem? This was working with WordPress 3.4.1
