Error at login: attempt to call global 'GetRealmMaintenance' (a nil value)

[Fairtale]

I am getting this weird error every time I try to log in.

Interface\GlueXML\CharacterSelect.lua:191:attempt to call global 'GetRealmMaintenance' (a nil value)

first thought the realm was down, but it has been like this the whole day.

I searched the forum but couldn't find anything related.

Any ideas?

Did you guys try to check your "DATA" folder? If there is "PATCH-O" present, please try to delete that.
