Hello, 

I was trying to upgrade from 7.2.0 and got the message: 

"Value cannot be null.

Parameter name: source

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.ArgumentNullException: Value cannot be null.

Parameter name: source

Source Error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

Stack Trace:

[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

PackFlash.DNN.Modules.SEO.HttpModules.SEOModule.GetPortalID(String portalAlias, String& out_portalAlias) +204

PackFlash.DNN.Modules.SEO.HttpModules.SEOModule.Application_BeginRequest(Object source, EventArgs e) +1112

System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +92

System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +165"

I've tried removing nulls from the PortalAlias table and manually adding whatever missing tables/sprocs I found, but no luck so far. Any advice on what exactly to look at? Thanks in advance!
