Project Detail Page (PDP): This Web Part was unable to load
I have recently moved a Project Server Farm from Production to a Test server that had done properly, But when I tried to open Project Detail Page (PDP), I encountered the below error:
The Project Detail Page (PDP) Shows “This Web Part was unable to load.”
I performed a quick investigation by editing the PDP, add a new Project Fields Web Part or any other Project Web Part to ensure that the issue is not related to project data. but the issue seems to affect all Project Web Part types.
The PWA URL still points to the Project Server PWA instance URL in Production.
Note: you should check the log file with the related correlation ID to can investigate your issue.
After moving a PWA instance to another farm, you may need to clear the PWA URL property to let the PWA instance read by default the current PWA instance URL.
Clear PWAURL property in Project Server using PowerShell
- Open SharePoint Management Shell as Administrator.
- Run the following code one by one.
$Web = get-SPWeb http://servername/pwa $Web.AllProperties | Format-Table
- Check the PWAURL that was set to old link actually.
