My DNN installation is hosted on GoDaddy. When I upgraded my local version of DNN from 8.0 to 8.02, no problems at all!! I uploaded the new upgrade files to production as usual. When I went to the site. The Upgrading DotNetNuke Version 8.00.02 screen appears and under the Installation Status Report it says "There is an installation currently in progress. Please try again later." Anyone know what would cause this error and how to fix it. Thanks!!

Hopefully you mad a backup of your database and files before you started.

If you did, I would restore the site, and try the upgrade again. I would also suggest that you make sure that you "unblocked" the upgrade package before extracting the files.
