Parked domain not working anymore

[ffbreakfast]

Hello

(General info : )
cPanel username : ffb
x10hosting subdomain : http://ffbreakfast.x10hosting.com
Parked domain : http://flashforbreakfast.com

So I had this parked domain (http://flashforbreakfast.com) which worked for a long time but recently I've been getting this "Great Success ! Apache is working on your cPanel..." page even though the x10hosting subdomain (http://ffbreakfast.x10hosting.com) still works AND i can still access my cPanel trough the parked domain (http://flashforbreakfast.com:2082)
Also, through my file manager, all my files are there and works. And, my "Parked Domains" in the cPanel are empty. I've tried to add (again) my domain I get this error : "Error from park wrapper: flashforbreakfast.com is owned by another user."

Any ideas? :S

Thanks for your help!

Edit : I don't know if it helps but I'm on Cossack
