Within a SharePoint site that we’ve upgraded, we have an error showing when users navigate to a page :
Using some PowerShell, I was able to list the specific webparts on the page :
$web = Get-SPWeb http://intranet/Services/Finance $list = $web.Lists["Pages"] #get the page (listitem) $item = $list.Items #get the webpart manager $wpm = $item.File.GetLimitedWebPartManager('Shared') $wpm.WebParts | select id, title
And somehow, there is a duplicate GUID for a certain WebPart :
The next step is to remove one of those webparts from the page – following on from the PowerShell shown above :
#get the webpart using #3 $wp = $wpm.WebParts #check which one we've got $wp | select id, title #delete from the page - and update $wpm.DeleteWebPart($wp) $item.Update()
That outta do it – and your users will be able to browse to the page.
NB. You might have to checkout the page also – and then verify which webpart you need to remove – be careful !
