Hello all,

I use DNN453. 
After translation with the langauage editor, logging out from the portal and trying to enter the portal (Login), I get:
"Object reference not set to an instance of an object"

Stack Trace:

[NullReferenceException: Object reference not set to an instance of an object.]
   DotNetNuke.Entities.Portals.PortalSettings.VerifyPortalTab(Int32 PortalId, Int32 TabId) +404
   DotNetNuke.Entities.Portals.PortalSettings.GetPortalSettings(Int32 TabId, PortalAliasInfo objPortalAliasInfo) +2413

   System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +92
   System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +64

I installed DNN453 again and tried to copy my language resources. I still get the same error.

I made a language pack and installed it on DNN453. I still get the same error.

I made the installations on my computer and on a webhost. I stil get the same error

Can someone help?

Thanks Leupold for your answer.

I installed DNN453 10 to 20 times. Every installation failed with the same exception.
I Installed DNN441 instead and my problem disappeared.
So i use now only DNN441.
I don't trust DNN453.
After my experience, I will use DNN4.5 only after I will see there stabilization.

There are many problems in DNN4.5 with right to left language that doesnt exist in DNN441.
For example: to update a title in container there are floating "edit image" and floating "save image".
Try to use it with a right to left container and see what a mess it does.
Do not try to be smart when there is no need to be smart.
A simple click on the title, in DNN441 does the job nicely.

Thanks for your help

Hello Leupold,

How can I provide you?
I don't know your email.

In general, How can I send DNN errors to the core members?
