  1. We recently discovered a server running Microsoft® Search Server 2010 Express. The patch level seems to indicate SP 2010 SP2. Does that just require the SharePoint 2010 Foundation CU in order to be patched?

  2. Hello Stefan,

    I’m noticing Rss Viewer Webpart not working after December Patch. This is happening to our staging and production environment. This affects our SharePoint 2010 and 2016. Another person reported same behavior here:
    https://docs.microsoft.com/en-us/answers/questions/200319/sharepoint-2016-rss-viewer-web-part-does-not-work.html

    The error on the webpart is – “An unexpected error occurred processing your request. Check the logs for details and correct the problem.”

    Seeing – “System.ArgumentNullException: Value cannot be null. Parameter name: requestUriString.
