Do you have access to admin mode? If so, you should be able to reset the access rights.
Do you mean in the Admin Access Settings? When we click on the content, it takes us to an empty page.
Admin > Access Rights > Set Access Right or Admin > Tools > Manage Content if you're on latest version of Episerver.
I know I shouldn't do it. I know it is hacky. I know it is dangerous.
However, how can I change values in the database to make a page container available again? Someone changed the rights by mistake, and now it is unavailable.
Thanks in advance,
