Important: It is required to install both fixes (language dependent and independent) to fully patch a SharePoint server. This applies also to servers which do not have language packs installed. The reason is that each SharePoint installation includes a language dependent component together with a language independent component. If additional language packs are added later (only) the language dependent fix has to be applied again.

It is irrelevant which language you pick on the drop down in download center. Even the language dependent fixes are all in the same package for all languages.

After installing the fixes you need to run the SharePoint 2019 Products Configuration Wizard on each machine in the farm. If you prefer to run the command line version psconfig.exe ensure to have a look here for the correct options.

Please ensure to have a look at the SharePoint Patching Best Practices before applying new fixes.

  2. Hi,
    Search stopped working after applying the CU, it is giving the following error, I also cannot access the search config from the central admin page!

    The error:

    The base type ‘Microsoft.Office.Server.Search.Internal.UI.SearchResultsLayoutPage’ is not allowed for this page. The type Microsoft.Office.Server.Search.Internal.UI.SearchResultsLayoutPage, Microsoft.Office.Server.Search, Version=, Culture=neutral, PublicKeyToken=71e9bce111e9429c could not be found or it is not registered as safe.

    ** I added the following lines to web.config of the central admin site with no luck !

    Any idea how to overcome this error?

    Thank you for your great efforts.


    1. I ran the psconfigui.exe command and all is back working as it should be
