PowerShell - Delete Duplicate Quick Launch Nodes

Scenario:

• Site slow to load, resulting in an exception with a correlation ID
• ULS log error: PortalSiteMapProvider was unable to fetch children for node at URL
• Temporarily hide the quick launch so users can navigate to the site: SharePoint Designer 2010 > http://samplesite > Left Nav > 'Sample Site Name' > uncheck 'Display Quick Launch' > Save.
• Find the offending Quick Launch node by running the following SQL query against the content database. You should see many, many repeating entries: SELECT * FROM NavNodes
• Delete the repeats from the Quick Launch via PowerShell:
  
  $FindString = “Offending Sample Title”
  $web = get-spweb ("http://samplesite/")

  for ($i = $web.Navigation.QuickLaunch.Count-1; $i -ge 0; $i--)
  {
  write-host $web.Navigation.QuickLaunch[$i].Title "heading deleting...... "
  $web.Navigation.QuickLaunch[$i].Delete()
  write-host "heading deleted successfully !!!."
  }
• Display the quick launch again.
