Spaming realmlist advice

Hi. I followed the guide instruction to change my realmlist, so i have the new one set realmlist logon.warmane.com
But the game is all the time asking me to change it. I tried to erase cache files but it doesnt work. It makes me so difficult to chat with others because is allways spaming. What can i do??
Thank you

If it's still spamming then it was not changed properly. Check what you changed again.

Make sure to double check it because there are 2 different locations. Data\enUS\Realmlist.wtf and WTF\Config.wtf

Perfect, it was the problem. Thank you a lot.
