Also getting no tooltips in my OneBag and only this error:
Error: attempt to index local 'self' (a nil value) File: Interface\FrameXML\ContainerFrame.lua Line: 602 Count: 1
tried to fix line 57 as mentioned earlier, but didnt work out... :( any ideas?
Was having the same problem. Couldn't figure out how to fix it as Interface\FrameXML\ContainerFrame.lua was nonexistant on my machine. =/
Finally disabled all addons and re-enabled one by one till I found the culprit.
Had my BF log in and see if he could recreate the error/solution since he also used MonkeyQuest. Error was there, disabling the addon corrected it.
Hope that helps someone else too.
