I am trying to fix all pre upgrade errors we have, but now i am stuck at two issues.
1: The following web part(s) are referenced by the content, but they are not installed on the web server
Id = 530cf774-77de-679d-f9a3-de8e74999ba8, Type = Unknown, Reference = 5, Status = Missing
This one comes up on all our SharePoint servers except for one of our FE servers. Now i searched for the site this webpart
is on and with ?contents=1 and see if there is a error webpart. But this is not the case. Anyone has a idea how i can find out what the problem is here?
The following setup file(s) are referenced by the content, but they are not installed on the web server
