@1: 403 can mean a few things. First, as you pointed out, it could mean you do not have access to the file for any number of reasons. However, it can also mean the web server does not have permission to read the file. On Unix-like systems, which are responsible for serving most Internet content, each file and directory has permissions associated with it, which determine who can read, write, and execute. If the web server process doesn't have the read permission on the file you want, or I assume the read and execute permissions on one of the folders it needs, or if a few other things aren't quite right, it will throw an error 403. There is nothing you can do about this, the webmaster, server administrator, or the user who has space on the server needs to correct the problem.
