There is a little bug that can occure when you play around with privateservers. I got this, and found a way to get over it.
I though about making this guide for you all, so you don't have sturggle in pain if you face this. It's easy to fix^^
If you Addon screenlooks like this for somereason;
Then go to your World Of Warcraft Root Folder!
Here;
Then find the Repair button from there.
When you doubletap the repair this screen will show up:
You can select all of them. The middle one isn't a must where you can keep your bindings and settings ^^ But the other two you have to have checked!
Click Reset And Check Files
And let it finish. After it's done reset the Realmlist.wtf files data again to:
CODE
set realmlist login.remnantsofchaos.com
You're done!^^
Mac Users Attention!
Since you Do Not have Repair button. You can delete your Interface folder. Problem with this is that you actually lose everything.
Sorry I can't provide you with Mac Screenshot location of Interface folder. But I still took Windows one:
It still should be located in the root folder of World Of Warcraft.
