Error showing Developer Dashboard in SharePoint Foundation 2013

Question

Hi everybody,
we have a SharePoint Foundation 2013 farm with SP1 and CU Nov 2014 applied (15.0.4667.1000). We have enabled developer dashboard and when we try to open it a new browser window appears with the followed error:
Server Error in '/' Application.
Cannot make a cache safe URL for "microsoftajax.js", file not found. Please verify that the file exists under the layouts directory.

This error is reproduced in all our enviroments, which has applied the same level patch.
Is this a SharePoint bug?

Answer 1

I am using following power shell command.
$contentService = [Microsoft.SharePoint.Administration.SPWebService]::ContentService
$devDashboardSettings = $contentService.DeveloperDashboardSettings
$devDashboardSettings.DisplayLevel = "On"
$devDashboardSettings.Update();
I have used this commands on Sharepoint 2013 Foundation. In that, it shows small icon for DD. But when I am clicking on it, it doesn't show anything. Just blank screen. When I used same commands with Sharepoint 2013 server vesion, these commands works for me.
Does this mean that, in Sharepoint Foundation, It doesn't provide Developer Dashboard. ?
Please comment below , if you have any idea.
