Hi, we upgraded our Intranet site from 4.4.1 to 4.8.2 last week. That went smoothly and everything worked.

Now we have just tried to upgrade some of the modules to the latest versions. Documents was the first module i tried, upgraded fine but now we cannot open any documents.

This is the error:

Error: Documents is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: The type initializer for 'DotNetNuke.Modules.Documents.DataProvider' threw an exception. ---> System.TypeInitializationException: The type initializer for 'DotNetNuke.Modules.Documents.DataProvider' threw an exception. ---> System.ArgumentNullException: Value cannot be null. Parameter name: type at System.Activator.CreateInstance(Type type, Boolean nonPublic) at DotNetNuke.Framework.Reflection.CreateObject(String ObjectProviderType, String ObjectProviderName, String ObjectNamespace, String ObjectAssemblyName, Boolean UseCache) at DotNetNuke.Framework.Reflection.CreateObject(String ObjectProviderType, String ObjectNamespace, String ObjectAssemblyName) at DotNetNuke.Modules.Documents.DataProvider.CreateProvider() at DotNetNuke.Modules.Documents.DataProvider..cctor() --- End of inner exception stack trace --- at DotNetNuke.Modules.Documents.DataProvider.Instance() at DotNetNuke.Modules.Documents.DocumentController.GetDocumentsSettings(Int32 ModuleId) at DotNetNuke.Modules.Documents.Document.LoadSettings() at DotNetNuke.Modules.Documents.Document.Page_Load(Object sender, EventArgs e) --- End of inner exception stack trace ---

What does this translate to in leymans terms?

Many Thanks

Actually, if he is installing the latest 04.00.00 version of the Documents module, there should NOT be a DotNetNuke.Modules.Documents.SqlDataProvider.dll in the /bin folder. I have seen this similar error when upgrades to the core framework and modules have not successfully removed obsolete .dll files.

Try REMOVING the DotNetNuke.Modules.Documents.SqlDataProvider.dll from the /bin folder.
