[Fixed]: The page ‘catalogs/DeviceChannelMappings.aspx’ allows a limit of 11

The page ‘catalogs/DeviceChannelMappings.aspx’ allows a limit of 11 – I was fixing the SharePoint 2016 search issue where I was getting the below error while searching anything in the SharePoint 2016 search box:

“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.”

Then got some solutions from Google, where it was mentioned we need to add the below entries on the web. config file of the issued particular web application:

<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>

Once I added the above entry to the web. config file, it triggered another issue

Sorry, something went wrong
The page '/_catalogs/masterpage/__DeviceChannelMappings.aspx' allows a limit of 11 direct dependencies, and that limit has been exceeded.

Then, how to fix this issue?

Solution: The page ‘catalogs/DeviceChannelMappings.aspx’ allows a limit of 11

The above problem easily can be fixed by editing the web. config file.

If you insert more than 10 user controls on a master page, we might get an error similar to this:

The page ‘/_catalogs/masterpage/__somefile.aspx’ allows a limit of 11 direct dependencies, and that limit has been exceeded.

We can easily increase this “DirectFileDependencies” limit from the SharePoint web. config file.

Steps to edit web.config file in SharePoint

1. Browse to C:\inetpub\wwwroot\wss\VirtualDirectories\ (in Web Front End Server)
2. Open the folder corresponding to your Sharepoint web application.
3. Edit the web. config file.
4. Search for the text “safemode“.
5. Change the property DirectFileDependencies from 10 to a value your choice, here I have changed the value from 10 to 20, the default value is 10.

<SafeMode MaxControls = "200" CallStack = "true" DirectFileDependencies = "20" TotalFileDependencies = "50" AllowPageLevelTrace = "false" >

6. Perform an iisreset command and that’s it, the issue will be fixed.

Summary: The page ‘catalogs/DeviceChannelMappings.aspx’ allows a limit of 11
