Turn on the display of script errors
Supported on At least Internet Explorer 7.0
What it does
This policy setting specifies whether to display script errors when a page does not appear properly because of problems with its scripting. This feature is off by default, but it is useful to developers when they are testing webpages. If you enable this policy setting, the user is shown script errors when a page does not appear properly because of problems with its scripting. The user cannot change this policy setting. If you disable this policy setting, the user is not shown script errors when a page does not appear properly because of problems with its scripting. The user cannot change this policy setting. If you do not configure this policy setting, the user can turn on or turn off the display of script errors.

- The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
- Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
