Just not my week... What is this error and how can I fix it?

I'm a huge noob here... so thats going to be the hard part of trying to help me but ive made a new team and starting to try advanced set ups and i hit a snag.

Interface\GlueXML\OptionsPanelTemplates.lua:258:at tempt to call method 'GetValue'(a nil value)

I have no addons other than Isboxer running atm... it crashes WoW and i find my self at the log in screen with this error? what do u need from me to help get this resolved and how do it get the info?

Thanks

There is a repair option somewhere in the launcher, you can try that (can't search for it right now.) It seems like a pretty serious error, if I'm reading your message correctly. Maybe you can try a fresh install of wow?

There is no separate repair tool or function anymore, it's integrated into the launcher and should work automatically. Try launching the game from the Launcher, not through Inner Space {and as admin, probably}. Log all the way in and all the way out and see if it autocorrects the error.

Great work... Tyvm guys and gals. That seemed to have worked some magic :D
