Hello, this post was all about updating to Joomla 5.1 from 4.4.4. I tried updating, and got error 500 on front end. Back end OK.
I have reinstalled old 4.4.4 site as this is a live site. I supplied the error message to you that I received on front end at beginning of this thread. It was shared with Moderator only. Can you still see this or would you like me to post again?
