More information:


  1. After installing the security patches our SP2013 farm ran in weird errors. We see that the ECB is not working as expected, and the language templates are missing in the Layouts folder. Is the version mentioned above is a stable version for SP2013?


  2. Hello,
    We applied the May 2019 Windows patches and now SharePoint search crawl is totally broken. Anyone else noticed the issue?


  3. Hello,
    Same issue on our SharePoint 2013 server after May2019 CU: search crawl is broken.


  4. Hello,

    after applied the KB 4464564 – on our Sharepoint 2013 server. Links to lookup-values in our views are messed up. I get error message “a potentially dangerous request.path value was detected”.

    Anyone else has this issue?


    1. Hi Daniel,
      I would recommend to open a ticket with Microsoft support to get this analyzed.
