OK, fixed it. For the ppl with the same problem, to change the logon from US to EU, in your worldofwarcraft/data/enUS  change the enUS to enGB and when u start the game it will atomatically create the stuff that it needs.

mhm I see, thanks for the help m8. Blizzard removed the realmlist.wtf from the game, now I don't know what to edit really :)

As I wrote on the previous post ... tried it on Twisting Neather ( which is EU realm aswell like sylvanas) and it shows US aswell, so I guess thats not my problem buddy, and even if it is tell me which file ti fix or what command to write.

It returns us.logon.worldofwarcraft.com but in tiwsting neather where it works returns the same when I type /script print(GetCVar( "realmList" )); so I dont think thats the issue bud :(

Amm can't rly copy the stats from my chat but compared the stat from twisting neather ( where oQ works) and sylvanas and the difference is only the line: 

my_realm    :X  unknown realm: Sylvanas

so how can I make it known :)

m8 I dont have tabs, oQ opens and all the tabs are blank, nada and thats only on sylvanas
 

amm typed what u said man and nothing happened. and When I click on the setup tab it doesn't show me anything its just a black blank tab, like all the tabs are :(
 

oQ doesn't work for my realm ?! help

Hia, my oQ was working just fine , then had to reinstall my Windows. Now istalled wow and oQ aswell and it doesn't wona work on my character on Sylvanas but still work for my characters in Twisting Neather. What is the prob and how can I fix it. Reinstalled oQ many times, still the same thing. I can see it in my addon list, I can open the oQ window with /oq, dont have minimap icon tho, and when I open the oQ window its empty. :(
