Ok, seems you have 0.8 and 8.1.5 installed and it the 0.8 version you have active. Threw me for a loop for a few minutes when changes I was making were not being reflected … I guess I was wrong 0.8 didn’t have the change for the visual editor. I made the necessary tweak and the visual editor works for you now.
I see you made changes to core template… not sure if there are any else, but if there are no other changes, I recommend migrating your changes to the new version. YOu do not want to fall too far behind.
The great thing is in newer versions I made it update safe to mod the core templates. See this:

Lastly, if I have not asked and you have moment, I would truly appreciate a review as they really do make a difference. Many thanks in advance!
