I copied a Master Page from a SharePoint Online site and started working with it on a SharePoint 2013 VM. When trying to load a page on the VM that uses this Master Page I get this error:
Unknown server tag 'SharePoint:FlightedContent'.
When looking up on Microsoft.SharePoint.WebControls namespace the FlightedContent
is currently listed, but greyed out.
Eventually I will re-deploy this Master Page back to the SharePoint Online environment but am wondering if there is a way to get around this error while working on the VM?
