I got a strange problem with my MOTD and RealmStatus in Roster. They don't work although I have GD and Freetype on. Is there anything else that could be causing problems for those two to appear?
Output from the rosterdiag:

I had the same problem. Its just blank. Not even a pretty picture declaring the absence of a server, just black.

I accidentally broke my roster and was waiting around for someone to post in order to 1) call me an idiot for not checking all 19 million posts about wowroster and then 2) directing me to a fix that works when i decided to take matters into my own hands.

I re-uploaded all the files from the zip to the server except the install.php and install directory.

Presto, it works.
