UnGhosting Customized Page Layouts with PowerShell
Post date: Aug 31, 2015 10:10:36 AM
Sometimes you end up in a solution where someone have been kind enough to use SharePoint Designer to edit a Page Layout. This means that you are not able to change the Page Layout through your deployed code, in a package. Changes made in the development environment doesn’t show up in production. Your Page Layout is in a Ghosted mode of its origin, and we need to Un-Ghost the Page Layout to be able to change it from a package created in our development environment.
Thus you use this script to first find out which Page Layouts have been changed, and uncomment the Revert Content Stream to actually change the Page Layout back to an UnGhosted mode.
$s = Get-SPSite https://siteCollectionUrl
$w = $s.RootWeb
$ps = New-Object Microsoft.SharePoint.Publishing.PublishingSite($s)
$pls = $ps.PageLayouts
foreach ($pl in $pls)
$f = $w.GetFile($pl.ServerRelativeUrl)
if ($f.CustomizedPageStatus -eq "Customized")
Write-Host "Layout page name: " -NoNewline
Write-Host "Status before: " -NoNewline
Write-Host "Status after: " -NoNewline
