I am getting a continuous stream of general exceptions on my sites relating to my own modules. The type conversion it is failing on is something that I misspelt in my <businesscontrollerclass> entry in my first few releases - this has subsequently been fixed, but somewhere DNN is still holding these type names - they are not in the main DesktopModules table, if i search all files on the installation I cannot find it - so somewhere in the DNN database there is some historic business class controller name and some processing that is failing ... but WHERE?

In DNN 4.8.3 the error (below) seems to be related to UpgradeVersionsList and I therefore assume it is something to do with keeping track of all modules versions. But I can't find anything obvious searching the database ...

... where do I have to remove this erroneous type name from to stop these exceptions.

Thanks for any help!

In DNN 4.5.1 I am regularly getting the following exceptions

Could not load type 'Twoic.Pallets.Web.Movements.Business.npPartnersController' from assembly 'Twoic.Pallets.Web.Movements'.

You'll find the entry causing the first exception in the DNN EventQue table. Look in the Attributes column for reference to that BusinessControllerClass. You will also note that the IsCompleted value for that row will be False (0). To stop the exception, either delete the row entirely or set the IsCompleted value to 1.

The second exception may also be related to a similar entry in the EventQue table of the second site, but my better guess is that it is being caused by reference to the deleted assembly as a Scheduled Job. Look for it in the TypeFullName column of the DNN Schedule table.
