We have multiple site collections in one webapplication and each site collection is in its own content DB. Now when I browse to one of the site collection, it gives me HTTP 404 not found error. And When I dig deeper what's causing it, I found below error in "Manage content Database settings" section of central admin:-
Database Schema Versions Not Responding.
Other site collections in that webapplication are fine and rendering without any issue.Any idea how to fix this "Schema version issue" for that one site collection?
