This happened to a few people, myself included. Id read the an addon might be the cause of it, but a relog might also fix it. I was about to disabled all addons and check, but a relog took cared of it. In you case, try disabling addons. GL.
You’re supposed to save the folders and you can put them back. But a Ui reset does more than most realize. All that hidden weird stuff can get fixed with a cache deletion and UI reset.
Not saying it would definitely work for you, but it does have its advantages.
There’s nothing a GM can do for a bug. You need to post in Bug Reports. All that does is bog down the ticket system.
The instructions say to just rename them. So if you did that, you may still have the old ones!
Rename the Cache, Interface, and WTF folders to CacheOld, InterfaceOld, and WTFOld.
Yes. Bugs aren’t something they can fix. Your other issue probably wasn’t a bug like this.
The ticket is in now, so see what you get back. But it’ll probably just be a template response about bug reports or sending you to Wowhead. Because they like doing that, too. lol
