[Fixed]: The base type ‘.Search.UI.SearchResultsLayoutPage’ is not allowed for this page

The base type ‘.Search.UI.SearchResultsLayoutPage’ is not allowed for this page – suddenly in SharePoint 2016, the people search has stopped working, when we have tried to search any users from SharePoint 2016, we got the below 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=16.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c could not be found or it is not registered as safe.”

Reason for the above error or issue:

Recently if you have updated any windows update or security update in SharePoint 2016 or a higher version of SharePoint, we will get into this issue, generally, it started happening after October 2020 windows security update in the server.

Solution: The base type ‘.Search.UI.SearchResultsLayoutPage’ is not allowed for this page

If you google around about this issue, we will get a lot of references to update the web.config file of the issued web application, most people say to add the below entry in the web. config file.

<SafeControls>
<SafeControl Assembly="Microsoft.Office.Server.Search, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" Namespace="Microsoft.Office.Server.Search.Internal.UI" TypeName="*" Safe="True" />
</SafeControls>

<PageParserPaths>
<PageParserPath VirtualPath="/*" CompilationMode="Always" AllowServerSideScript="True" IncludeSubFolders="true" />
</PageParserPaths>

However, for us, we just added the below line inside the <safecontrols> tag of the web.config file and it started working:

<SafeControl Assembly="Microsoft.Office.Server.Search, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" Namespace="Microsoft.Office.Server.Search.Internal.UI" TypeName="*" Safe="True" />

Note:

• We didn’t add the “<PageParserPath VirtualPath=”/*” CompilationMode=”Always” AllowServerSideScript=”True” IncludeSubFolders=”true” />” tag, still it worked, rather when we tried to add this tag, we endedup with some other error.
