With the script that we’re showing, you can reset the masterpage on a SharePoint site and get back to the default masterpage (Seattle). This command can be used by any SharePoint version, a few notes that I want the user to be aware before running this script.
- It’ll only apply to the site that you’re connected and not all site collection
- If you’ve custom masterpage with custom zones, you may have an error when accessing to pages because those zones don’t exist on the default masterpage.
- Make sure you have the $site variable with /
- On the $ domainUrl make sure you when the line without \.
- If you’ve other type of security on login check the other options to login on the PnP
