Also, what code do I use to get this red stuff: Is there a quick reference for forum codes?
The slanted apostrophe looking thing to the right of the 1 key on a U.S. keyboard. Put text in a pair of those and you get red text.
/etc/exports should have two entries, for the images directory and the dev directory, wherever those are. If you correct storageLocation= inside of /opt/fog/.fogsettings and re-run the installer, it’ll write the exports file correctly. The FTP path and Images path in the web interface should simply be the true path of where the images are.
