@kellymetal I’m using Blacknight, shared linux.
Your’re right of course – but in my case it was the kick I needed to change hosting anyway. I was using PHP implementation 7.3.11 and I changed to 7.1.32 and it had no effect. I didn’t try any other versions.
I can confirm that moving hosting fixes this issue for me… I’ve been meaning to move anyway as my server responses were getting very slow and the dashboard was a pain. I moved to a basic namecheap/easywp starter package ($1 for the first month!), migrated using All in One Migration tool and the emails are sending perfectly in HTML now. Issue with PHP version with certain hosting providers perhaps?
Ditto here. As a long shot, tried replacing email templates from old version but no joy. Plain text works fine for now.
