E-mail confirmations not sending

I posted about this once before, but haven’t been able to resolve this problem. When a user signs up for one of our events, they receive no confirmation e-mail (despite the fact that I’ve selected this should happen for every event). I’ve tried toggling this on and off, adding new events, etc. But for some reason, no confirmation e-mail gets sent. What’s weird is that they used to get sent without a problem.

I’m using the current version of EE, as well as the most recent version of WP.

We had the same problem. Looking at the mail log we found the following error: “Transaction failed: Duplicate header ‘MIME-Version'”.
It seems that WordPress ads its own MIME header, so this results in a duplicate MIME header. Quick fix is te remove the mime header from the file:
/event-espresso/includes/functions/email.php in the function event_espresso_send_email. replace line $headers = “MIME-Version: 1.0\r\n”; with $headers = “”;
This worked for me.
