Message saying forbidden, locked site

[goshalim]

Hi ,

My forum site is www.canarybreeder.net

and it gets this message if you try to acces it

Forbidden
You don't have permission to access /up/ on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

We had an issue last night and everyone could see the directory and access it so one of the mods somewhere in the directory menu ticked the Boxes of user and World to read and write but not to modify, only the owner was left ticked read write and modify

but now no one is able to enter and we get the previous message


Is it possible to solve this and re-set via ftp?
how can we access the root folder via ftp since hosting provider is away and everything it seems that is locked ?
Most propably the server autolocked it ...i dont know.

( up ) is my root folder .
Can you help me please?
Thanks
