Xrystal:
I found this change in TitanPanel forums that might help you:-)
Change:

local serverName = GetCVar("realmName");

to:

local serverName = GetRealmName();

I ended up going through all Titanpanel luas and replacing GetCVar("realmName") with GetRealmName() with Notepad++ and it's working now.
