I have restored the old web.config, but still the portals will not come up & getting :

[code]
[NullReferenceException: Object reference not set to an instance of an object.]
DotNetNuke.Entities.Portals.PortalSettings.GetPortalSettings(Int32 TabId, PortalAliasInfo objPortalAliasInfo) +91
DotNetNuke.Entities.Portals.PortalSettings..ctor(Int32 tabId, PortalAliasInfo objPortalAliasInfo) +82
DotNetNuke.HttpModules.UrlRewriteModule.OnBeginRequest(Object s, EventArgs e) +2677
System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +92
System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +64
[/code]

Seems as though it cannot find portal alias, even though I have gone into the SQL Server and ran the Stored Proc and it comes back with the portal ID ????

Can anyone help??

Cheers

Dan

Thanks, it seems as though it was using instances and was logging in as the aspnet user and that was the new setup using instances, when I have changed the login details and they seem correct, the system just hangs when I try to go to the default portal, get errors in event viewer about process threads being dropped???

Mitchel I could kiss you, thanks for that, all back up & running (albeit with a strage [L] in front of Login & Register & all the users online stuff

Thanks Again that has saved me from further hours trying everything

Cheers
