Can't reach update Server and LOTS of Errors in game

[Murthol]

Hey there,

first of all_ thank you for the regular updates about the DDoS and all the work you guys put into getting the servers stable again!

Now for my problem:
I can not reach the update server at the moment and tried playing via the local version. It starts up okay but has lots and lots of errors and is also displaying my UI wrong. (Errors, all keybinds gone, keyboard input does not seem to work, ...)
Is that a known issue?
I first noticed it the day before yesterday as far as I remember.
Most Error messages I got so far are from GlueXML(AccountLogin.lua:21) and FrameXML(GameTooltip.lua:95 and ActionButton.lua:377).
I attached some snipping tool pictures from the errors I was able to find and reproduce so far.
Ingame error messages are from the loading screen and one character. Windows error message is from another character.

Hope all the weird trouble will soon calm down; Thanks again for all the hard work. I really enjoyed your Server before the DDoS.

Kind regards
Murthol

I'm getting similar issues. Everything was fine last night but when I tried to log in today, I got the prompt to update the launcher to 1.8.3 and that's when this all started. I'm getting constant errors and I can't interact with the UI.

I've disabled all of my addons, mods, and deleted the WTF folder.

Ended up deleting and redownloading the game and that seemed to fix it.
