Re: HOW CAN I RUN SETUP.SH?
setup.sh is a script that resets permissions for specific directories so that users can write to them. If your server runs Linux, you need to SSH (remotely login) into the server and run the script. Alternately (and I am not recommending), you could manually do the permission changes if you have a cPanel or similar web interface to the files on the server.
You need to make the directories that are used for mods writeable by the web server so you can upload the appropriate mods.
