As the thread is listed I keep having this issue, my wife and I just started playing the game again. And decided to make new characters yet each time we make a character ALL the addons turn on when we get into the game, even though we had disabled all of them before logging into the game. I noticed some other posts about a similar issue back in October / November but did not see any solution to fix the problem
The solution is to do a full UI reset.
I have this problem as well and I did a full UI reset as they said to do and it doesn’t work. The addons I am using are up to date. After renaming the wtf folder I now keep getting a prompt to disable the addons.
