I am unable to do a full scan in the auction house with the latest version. The button never seems not to be clickable or never illuminates.

Im having the same problem
did you fix it?

Came here for this, only I'm also getting an error. For clarification, this is on Classic Hardcore. Even disabling all other mods, or deleting all saved variables and reinstalling has not fixed it.
