Yep, it's all geek to me.
Thanks for the explanation. Just to clarify, I can't use man chmod (guessing that "man" means manual/documentation on chmod commands?) b/c I don't have shell access through my web host, and I've never used Unix before.
I'm using an FTP program (Filezilla) to chmod permissions.
So, for the first command, that would be chmod 777.
And the second command would be chmod 777 for 3 files/folders: "logo.gif" "tempdir", and "templates_c."
Yes? Did I get that right?
