When clicking the "Save" link, I get a bunch of server errors, and then a bunch of ascii code, which I think is the file data.
Here are some of the errors:
Notice: Undefined variable: CurrentBrowsingDirectory in /home/khaskins/public_html/pickup/index.php on line 1170

What version of the filebrowser are you using? I know I released one version with a bug in it after an update. The latest version should fix that bug. And keep in mind when upgrading that there is no need to replace your config files.
