Rick - I just figured it out. The path in the "Attachments" section got changed to "/uploads" instead of "/attachments".
That was a dumb mistake by me who ran the install script instead of the upgrade script. I paid dearly by having to recreate all the settings manually in the control panel.
It appears to be back to normal since I fixed it. I just need to move any new uploads into the attachments directory now.
Thanks!
