Raid Finder Problem

Hello there,
I would be thankfull if someone could help me with a problem.So recently i started playing again on this server after a 2-3 month break.I got some gear and everything and tried searching for raids,but it seems like my raid finder interface is blank.I can select role(dmg,tank...) but everything below it is blank.The dropdown menu where you can select a specific raid says that all raids are disabled.
So does anyone know cause of this problem?
Thank you
The server is frostwolf

Anyone?????
