i have a customer portal with the dnn version 7.0.6 and the portal settings look like this:

and each portal has three languages - de-de (default), en-us and tr-tr

i wanted to upgrade to the version 7.1.1 
but i always get an error:

Server Error in '/' Application. 

Collection cannot be null. 
Parameter name: c 

[ArgumentNullException: Collection cannot be null. 
Parameter name: c] 
System.Collections.ArrayList..ctor(ICollection c) +9363279 
DotNetNuke.Entities.Portals.PortalController.GetPortals() +209 
DotNetNuke.Common.Initialize.CacheMappedDirectory() +39 
DotNetNuke.Common.Initialize.InitializeApp(HttpApplication app, Boolean& initialized) +174

System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +148 
System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +75

i looked to the portallocalization but there everything looks fine, so i'm not sure if my portal domains maybe the problem.

thanks for help

best regards
