foreach($web in $site.AllWebs)
{
  #Iterate through all Lists
  foreach($List in $Web.Lists)
 { 
 #Get only document libraries & Skip Hidden 
  if( ($List.BaseType -eq "DocumentLibrary") -and ($List.EnableVersioning) -and ($List.Hidden -eq $false) -and($List.IsApplicationList -eq $false) ) 
     {   
   #loop through each item
      foreach ($item in $list.Items)
      {
    if($item.File.Versions.Count -gt 0)
    {
        # delete all versions
     Write-Host "Deleting $($item.File.Versions.Count) Version(s) on: $($web.URL)$($item.URL)"
