Permission denied files directory

[Abstract]

Hi Everyone,

We're having a problem in the staff admin. When a ticket has been created and we want to reply with a perdeterminded reply. We're getting the following error messages:


-------------

[domain name of site] :the original domainname is changed in this message to [domain name of site]


Its a permission problem, but the files directory has the permssions 777. The index.html file inside this directory has the 777 permission, but the *.js files all have the 644 permissions.

Anyone has any idea?

Thanks Arian
