Try removing 1 addon at time to see if it is incompatibility. Many addons stopped working when Miko patch came out. That is, if you are using any.
If you aren’t using addons, try repair the game, but first, to not have to do all the work again, make a copy of the release text file and the patch folder with all the files in it. Then rename the new folder and file, and rename the old ones to their original and try again.
Forgot to post that i am in game right now:
