I finally got around to performing the update. I did the uninstall of the old version, and installed the new version, but when I clicked on the "Settings" link in the admin panel, I got a 404 not found error for the settings form. I removed the update, and tied uploading again, but the same thing. I deleted again, and re-installed the previous version, and tried to just do the update via the admin panel, but when I clicked on the "Settings" link this time, it opened a site page with a not found heading, so I went back to version 6. It is working fine. Haven't seen anyone else having this issue with the latest version.
