Hello to all,

I have a problem with the site for Upgrade from 7.2.1 to 7.3.1.

The Site is on a IIS Windows 2008R2 Server with SQL 2008R2

Other site on this Server hade no problem with Upgrade.

Steps that I make:

Backup from the working site

Copy the DNN 7.3.1 Upgrade file

When I now connect to the site, then I see this:

Value cannot be null.

Parameter name: source

[ArgumentNullException: Value cannot be null.
Parameter name: source]
   System.Linq.Enumerable.SingleOrDefault(IEnumerable`1 source, Func`2 predicate) +599
   DotNetNuke.Entities.Portals.PortalAliasController.GetPortalAliasLookupInternal(String alias) +287
   DotNetNuke.Entities.Portals.PortalAliasController.GetPortalAliasInternal(String httpAlias) +38
   DotNetNuke.Modules.ActiveForums.ForumsReWriter.OnBeginRequest(Object s, EventArgs e) +437
   System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +80
   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +165

What are the problem?

Thanks a lot

Axel

Hello,

I controlled, the entry PortalID seems to be correct.

The Site work also in the Moment without problems.

But after the Upgrade Files are copy to folder, the site not start again.
