I have same problem! :(

install 1.8.6 and watch your general chat area when you log in. 

if there's an error on login, it will show it

Ok the problem still there...
May i ask if there is a chance any Suite of addons might bug oqueue? 

to check for addon conflict... dsiable all addons except oqueue and log in

have done this... what i mean is when i dl a pack of addons wtf config etc i might dled something that harms oqueue?
like a sertain file or anything?

Found the problem at last! dont know how to fix. help me plz

Its says  : OQ error initializing
                realmlist: us.logon.worldofwarcraft.com
                error: Interface/Addons/Oqueue/oqueue.lua.22892:attempt to concatenate a nil value

what i do?

I have the same problem with blank Oqueue, and while Oq is enabled i can't open any item link ingame, if it is gear i can see what they look like (Ctrl-Click). Also everytime i open/close the map Oqueue starts but it's blank

Same problem. Everything worked up 1.8.3, but when I loaded1.8.5 and 1.8.6 all I get when I log into the game is I only have 1.6.0

Dead I repsonded to you in the other thread.

Tafos, and useroi, your best bet wil be to PM Tiny, or catch him on the WoW public vent. I am not sure about your issues. 

I finally got it to work, had to delete every file of Oqueue off my computer and reinstall oqueue. Please, unless there is a major change to WOW, leave oqueue like this until the next expansion. This is almost as irritating as DBM getting updated every month.
