Hi, so what I found is that there is a list of folders that must have permissions setup individually. They are listed under "Site-->System Information--->Directory Permissions" If they are unwritable, then Joomla will not function properly. I had even better success with this when I did this from the start, with a fresh installation. I made the CHMOD changes via FTP and made Group permission 6 - to write, ex. 664. I left the public permission the same to keep things as secure as possible.

The list should look exactly like mine below.
