Latest update = internal server error
I see that several others have already reported this problem, but I wanted to make another hand raised for the issue. We have experienced the same problem with the latest update - email testing doesn't send, preview in customizer doesn't load, no emails being sent and front end result = internal server error.
Yep, same issue here. Specifically, the error is on line 802 of ec-email-control.php.
This issue cause me more headache tonight than you could possibly know. We have several processes that happen after an order is placed and when this bombed, none of them fired. It created a huge mess.
Please test your updates before releasing them.
