Cathal, Thank you for replying.  I copied all the files to the bin folder, but I am getting the same error.

Something's still going wrong with the creation of the provider instance, please take a look at your web.config and ensure that the logging node has the correct setup (compare it to the one in the development.config file). Also, please make sure that the ~\Providers\LoggingProviders\Provider.DBLoggingProvider\ folder is there.
