I followed the README file and I can't FIND the directories they are talking about. I have the back up .gz I took before doing the upgrade so I untarred in on my PC and did a search for this one directory they say we need to use and it's not there. I posted the link to the support thread I started so we'll see what they come back with.
That's all I can do right now. We'd run into this problem at some point because we were still running on PHP 5.x and I had no choice but to move to at least 7.0 until I get two other sites that I host for paying customers upgraded and then I can move to php 7.3. However, being on 7.0 give us a lot more time than being on 5.x
