The database backup works fine now. As for my OS and MySQL versions, I'm running RedHat 7.2 and MySQL 3.23.48.
Thanks,

Or you can add this to the top of all the admin files.
include_once('/path/to/geeklog/config.php');
I've installed above the public web-tree so don't know if its an issue with a 'normal' install. Think some of the 'out of the box' files had this already, maybe not. Has worked fine for me.
