Hi Peter,
I just attempted to upgrade DMX 3.5.6 to 5.3.6. The installation appeared to go fine. No errors where thrown when installing. However, when I go to the page where I'd placed the module, there is an error that says:

A critical error has occurred.
The type initializer for 'Bring2mind.DNN.Modules.DMX.Data.DataProvider' threw an exception.

The container for the module is still there, but when I attempt to view it's settings, I get the following error:

Error: is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: The type initializer for 'Bring2mind.DNN.Modules.DMX.Data.DataProvider' threw an exception. ---> System.TypeInitializationException: The type initializer for 'Bring2mind.DNN.Modules.DMX.Data.DataProvider' threw an exception. ---> System.ArgumentNullException: Value cannot be null.

Any ideas on what this means?

Also running DNN 5.4.2

Hi Dave,

Make sure you delete the DMX.SqlDataProvider.dll from the bin folder. My guess is that it didn't get deleted as it had become read only.

Peter

Thanks Peter. I'm going to try to upgrade again this weekend. I'll let you know how it goes.

Dave

Success! Thanks for your help, Peter.
