same problem, convert to battlenet error

[jissisMan]

same here, will it be resolved or is it just a case of "it is what it is"?

[IremoftheSands]

Was experiencing this error earlier. Change your realmlist to: "logon.warmane.com"

[RemyRae]

Where is it? can't find it anywhere in the MoP files

For Everyone struggling, Please try below as previously shared by Moderators

Go to your WTF folder then open Config file and on the third line make sure it displays like this
SET realmlist "logon.warmane.com"
