hi choco, im having some problems with scape's forums, im wondering if u can help me out.

whenever i try to do something i get this error here :

Authorization mismatch - please go back and try again. If you have been trying to access a function incorrectly, please use the proper method.

i cant post, cant change my avatar/sig or anything. I tried making a new account but they said the forum isnt accepting new registrations.
Im pretty sure my account is fine seeing as i have 0%warn level, hope u ca help me out here, ty
