Kentico Required document no longer exists

Question

I have a Kentico 5.5 website and some custom document types. When you try to edit HomePage in CMSDesk it says that the Required document no longer exists, select another document.

I did not delete HomePage, but the document type was missing. Therefore, I restored the type of the document by exporting and importing it from another site of mine. The error is still present.

When I create a new home page with the same type of document, it shows that this site has no content, go to cmsdesk

Is something wrong with my document type or is my DB just corrupted?

UPDATE: I imported a new document type from another site along with the page template and role. Then an error occurs. I think it resets the main document type or some other related file.

Answer 1

It turns out that I imported the document type, and it was from another server, where the identifier was not synchronized, so the new document type overwritten the old document type with the same identifier. Identifiers are consistent, so if you import from one site to another, be very careful to always have all the same types of documents and create them all in the same order.

Answer 2

This happened on the intermediate site once. We tried several things in kentico and directly manipulated entries in the database, but could not sort it. As a result, we exported objects from the old site, installed the site and imported objects from the old site, and we returned and worked in 20 minutes. NTN

Answer 3

Perhaps try adding a new homepage and change your site settings to use it as your default homepage.
