I've made a copy of the file, just in case. But changing enUS to enGB and deleting the realmname line seemed to do the trick.

Thanks for the reply... Found the file. Opened it with Notepad and used ctrl-F to find "realmList" - but the file doesn't contain this word. It does say:

SET realmName "Aerie Peak"

- and -

SET locale "enUS"
SET installLocale "enUS"

Can I safely change (into "Hellfire" and "enGB") or delete these lines (or the file entirely)?

What about switching back to US, do I have to do this everytime?

How to switch between US and EU?

All google search results lead to 404 error - and since there's no search function on this forum either, i'll make a new thread. Sorry if it has been answered before, I haven't been able to find a solution.

TL;DR how to change us.logon.worldofwarcraft.com to eu?

I play on both a US and EU server. oQueue works fine on US. However, on EU I'm seeing the vx.xx + empty screens... Typing /script print(GetCVar("realmList")); in chat shows: "us.logon.worldofwarcraft.com". I've tried reinstalling the addon, clearing cache, oQueue wtf / lua files, everything i could think of... Nothing helped. How can I easily switch between EU and US, i figure it's not showing anything because the realmlist is incorrect. Any help is appreciated, ty.
