Hello

I'm trying to upgrade a site to EPi 7 from EPi 6.

I have upgraded with the deployment center and fixed all errors in the solution.
It works fine to surf to the site and go to the edit and admin UI.

But in some situations in the edit/admin UI I get an error.

For example when pressing some of the page types in admin in the page type tab. Then i get the following

Server Error in '/' Application.
Object reference not set to an instance of an object.
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.NullReferenceException: Object reference not set to an instance of an object.

Source Error:

And another place when somethings goes wrong is when pressing the forms-edit button in the edit mode for some pages but not for all. Then i receive this error

Server Error in '/' Application.

Perhaps some issue with TinyMCE by looking at the stack trace?

Anyone got any ideas?
