UIParent issue. Can't click parts of screen where it goes

Came back from MoP, and I’ve been getting addons ready. There’s this hidden green block close to the center of my screen, where I can’t click or interact anything within it. It’s draggable while /framestack is up. I disabled all addons I don’t use as I’ve heard disabled add-ons are loaded into memory anyway. Can anyone help?

Framestack:
DIALOG
–>UIParent.26013c3a0f60

I have an image I can show too, but I can’t post links here.

Try going into your World of Warcraft Retail folder and rename the Interface & WTF folder to something like WTFX and then restart the game. If it is no longer there it is probably a leftover from an old addon.

Thanks for the response! I ended up resolving the issue by removing all my addons, and adding them in one-by-one. Turns out it was an issue with CritLine’s AuraMonitor. Ended up deleting the AuraTracker folder and its .lua. It’s gone now, but thanks for the help!
