We have the following:
2016 SharePoint OnPrem with 6 servers.
After installing KB4486753 to our SharePoint Servers, our search services throws the following error:
Sorry, something went wrong 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=188.8.131.52, Culture=neutral, PublicKeyToken=71e9bce111e9429c could not be found or it is not registered as safe.
This is preventing not only users from searching and accessing our directory, but I also cannot access the search services in central admin. I have been working with MS to resolve the issue but after 22 days of this issue, they have been less than helpful.
What I have done so far:
- restart services on all servers
- adjusted the
web.configfiles to include the following code -
<SafeControl Assembly="Microsoft.Office.Server.WorkManagement.UI, Version=184.108.40.206, Culture=neutral, PublicKeyToken=71e9bce111e9429c" Namespace="Microsoft.Office.Server.Search.Internal.UI" TypeName="*" Safe="True" /> <PageParserPaths> <PageParserPath VirtualPath="/*" CompilationMode="Always" AllowServerSideScript="True" IncludeSubFolders="true" /> </PageParserPaths>
- Created a new DWORD called "LoaderOptimization" set to 1 in the HKEY_LOCAL_MACHINE\SOFTWARE\MIcrosoft.NetFramework area of the Registry Editor (with an IISREST)
Nothing has resolved the issue at all.
Has anyone experienced this and what was the resolution.
