I found a temporary fix for this.

Open the table 'DesktopModules' and enter NULL in the BusinessControllerClass field for the modules that you use.

I also found a fix for this.  Through reading some of the other posts...

It seems that the desktopmodules table has a supportedfeatures field that should be set to 0 or higher.  But sometimes when modules are installed they end up with a -1 so this causes the error.  Setting the fields to 0 when they are -1 fixes it, like so:

UPDATE [databasename].[dbo].[DesktopModules]
   SET [SupportedFeatures] = 0
 WHERE [SupportedFeatures] = -1

This is for SQL Server Express... don't know how it would work in the SQL page of DNN.

Although this thread is quite old, the same thing happened to me using version 5.2.2, so I wrote a blog post about the problem and potential solutions (with information taken from this and other threads):
