Hello,

I installed the DNN 4.3.5 which has the Forum module already with it.

Now when I try to add the Forum module I get the following error:

A critical error has occurred.
Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.

But however the module looks like is added.

And if I try to go into the Module settings I get:
Error: Module is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at DotNetNuke.Services.Exceptions.Exceptions.ProcessModuleLoadException(PortalModuleBase ctrlModule, Exception exc) at DotNetNuke.Modules.Forum.ModuleSettings.LoadSettings() at DotNetNuke.Modules.Admin.Modules.ModuleSettingsPage.Page_Load(Object sender, EventArgs e) --- End of inner exception stack trace ---

And in the Log viewer:

Why is this happening ? What could be wrong?

Thank you very much.

Christoc thank you for the reply. And yes I'm sure the two connection are filled with the right connection string .... the legacy connection and the other one.

Any other possible places I can look at?
