Hi,
I have the same issue.
I play on Mac OSX Mavericks. I downloaded the last version of oQueue today.
I used to use oQueue without a problem.
As usual, I downloaded the .zip, extracted the folder, deleted the previous oQueue folder in my Interface/addons folder, and put the new one.
oQueue does not show in my addons list, nor in game.
I never played on private server.
I play on EU server, but I play in North America (studies), however it wasn't a problem before oQueue did work for a year without a problem.
/script print( GetCVar("realmList") ) ;
It returns me eu.logon.worldofwarcraft.com (which I think is normal).
I did what "nicehs" wrote to the OP. In my Config.wtf, both locale values were enUS (which is strange to me). I tried to change one, then the other, then both with the value enGB.
It still does not work.
Could you help me?
Thanks in advance for your time,
Have a good day.
