Could not start mail function

Hi I am getting the error on registration for events "Notice
Could not start mail function." and no emails are being sent. Emails from the rest of the site are working fine.

It only seems to be happening for one event

Can you please assist?

Hi Christina

If it only happens with one event, then maybe there is something wrong with Notification Emails setting in that evet

Try to edit that event, look at Advanced Settings tab, check to see whether you have any emails entered into Notification emails config option. If there is email, try to empty it or use a different email to see whether it solves the issue?

Regards,
