Update from 3.5 to 4.13

After update was everything OK, site starts and I check for missed modules to install. After I install module danielgausi/contao-calendareditor-bundle which I use for frontend calender events I get followed:

What could be wrong with page with ID 34. I didn't change anything. Thank you guys for help.

Every Contao installation requires a root page. You must therefore make sure that a root page actually exists.

Attachment 358

Ofcourse, root page exists. Page worked fine until I install module for frontend calendar editing.

Can you please post a screenshot of the page structure?

Does the hierarchy fit?

Have you tried to save the root page again?

Yes, I did. Something must goes wrong with module Calendar FE edit. Module has property called Redirect page for adding events and if I set a specified page I get errors Page ID "65" does not belong to a root page and error No root page found. I think something must be set a little bit different because everything works OK under 3.5. Damn, any help please. Thanks guys.
