   Hi Stefan,
   After installed the September 2023 CU for SharePoint Server 2019, we are getting an error on custom user control. The error is “The control type ‘System.Web.UI.WebControls.TemplateField’ is not allowed on this page.”

         Hi, I am having the same issue after updating to September CU on my custom aspx page. There is alot of custom “System.Web.UI.WebControls.XXX is not allowed on this page” error. I have read KB5030804 and managed to fix some of them, however, some does not show up in the ULS logs (ex. ListView). Any recommendations?

   We’re getting similar error: System.Web.UI.WebControls.SiteMapPath.
   It was related to custom MasterPage. Sites were inaccessible, so it was reverted to OOTB masterpage. EventID on ULS is “tkau”. System.web.httpexception: The Control type ‘system.web.ui.webcontrols.sitemappath’ is not allowed on this page.

      Thanks Samir!
      I would recommend to open a support case with Microsoft to get this analyzed in more details.
      Cheers,
      Stefan

   Greetings, Stefan. Is there any knowledge of an issue with the “Items That Need Attention” view in the Modern UI that is causing “Something went wrong, Please Try Again or Refresh the page” messages? This all started for us after the August 2023 update. Thanks in advance for your response.

      Hi Daniel,
      I haven’t heard about such an issue.
      If you need assistance for this issue, please open a ticket with Microsoft Support to get this investigated.
      Cheers,

   Hi Stefan,

   Since installing the CU 2 days ago, we are finding that the “SharePoint Server Search 16” service is repeatedly disabling on one of our Search Servers and we are unable to unpause search once patching was finished, preventing Search from working correctly. Have you received many other reports of this?

   This is only happening for one Webapp in this farm. The search service for another WebApp within the farm is functioning without issue.

   Hi Stefan

   After installation of the binaries we see a high CPU load, the noderunner processes are consuming 80% CPU.
   I opened a MS Ticket just now.

   Best Regards,
   Ueli

   Hi Stefan,

   I installed Sept 2023 update in STG environment and when running configuration Wizard on any of the 6 servers in farm, it kept giving below error:

   An exception of type Microsoft.SharePoint.PostSetupConfiguration.PostSetupConfigurationTaskException was thrown. Additional exception information:
   Failed updating SecurityMode and ProtectionLevel in cluster. [Exception=System.Management.Automation.CmdletInvocationException: Cannot stop AppFabricCachingService service on computer ‘Primary Webserver name’. —> System.InvalidOperationException: Cannot stop AppFabricCachingService service on computer ‘Primary web Server’. —> System.ComponentModel.Win32Exception: The service cannot accept control messages at this time

   I disabled App Fabric Caching Service on Primary Web Server and configuration wizard was able to complete successfully on all 6 servers in our environment. Otherwise all 6 were showing same error as not able to stop the service on Primary web server.

   I will be attempting upgrade in PRD in few days, therefore wanted to check if it is ok to always stop this service before running configuration wizard?

   Thank You!

   Dear Stefan, All,

   For those who has MIM portal running on SharePoint Server 2019, after installing September 2023 CU it probably stops working. The MIM portal is throwing the error:

   Sorry, something went wrong
   The control type ‘System.Web.UI.HtmlControls.HtmlAnchor’ is not allowed on this page.

   There are some new requirements for deploying SharePoint 2019 and MIM. And the solition is to run a powershell script mentioned in the article – https://learn.microsoft.com/en-us/microsoft-identity-manager/prepare-server-sharepoint#prepare-sharepoint-to-host-the-mim-portal

   $f = get-spfarm
   $f.AddGenericAllowedListValue(“WebPartSupportedBoundPropertyNames”,”data-title-text”)
   $f.AddGenericAllowedListValue(“WebPartSupportedBoundPropertyNames”,”data-link-to-tab-text”)
   $f.update()

   iisreset

   Thank you.
