Permissions can be set in FILE MANAGER.
Permissions allow certain individuals to access or be blocked from files and folders. There are three levels of permissions: Read, Write, and Execute, and three levels of users: Owner, Group, Other.
Read is given a value of "4"
Write is given a value of "2"
Execute is given a value of "1"
An example permissions setting would be:
755
The first value, (7) represents the "Owner", who has permission to Read (4) + Write (2) + Execute (1) giving 7 total.
The second value, (5) represents the "Group", who have permission to Read(4) + Execute (1) giving 5 total.
The third value, (5) represents the "Others", who have permission to Read (4) + Execute (1) giving 5 as well.
Setting a file or folder's permissions to 777 (Owner, Group, and Others have full permissions) should be avoided, as it presents potential security holes in the server, especially on CGI scripts.
Typically, a setting of 755 is safe enough, while allowing ample permissions to run the script. Consult the documentation for whatever script you are trying to setup to find out what permissions each file and folder should have.
To set permissions on files and directories all you need to do is to go to your control panel ("yourdomain.com/menu") go to the File Manager, find the file you're looking for, and click on the link next to it that looks like "rw-r--r--" in the column entitled "Permissions". Once you click on that you can modify the permissions. "rwxr-xr-x" is the same as 755 (which is the general executable permission setting), and "rwxrwxrwx" is 777.
