When installing Wordpress on an Apache server, you may get a 403 error. Specifically, you might get this error when you try to access your site after an install.
You don't have permission to access / on this server.
This is so simple to solve. You simply have to enable script permissions on the serve. If you are on a host like Godaddy, this means that you go to the folder, select permissions and make sure the folder has Read and Execute permission for web users and Read, Write and Execute permissions for the Owner.
