Hi Support,
I have two lists on SharePoint Online which are List A and List B respectively and I have created a display form for List A from SharePoint Designer 2013. Then I edit the List A's display form and add List B on the form by web parts. It works fine til yesterday. However, error "The "XsltListViewWebPart" Web Part appears to be causing a problem. Unable to find the specified file." is displayed today. I am sure that I did not change anything in recent days. And I find that this error will be displayed because of List A Or List B hasused unique permissions. (click the button stopped inheriting permission on Lists Settings ->Permissions for this List)
I need to use unique permission on List A and add web parts of List B to List A form and I am sure that it works fine til yesterday. I would to know is any update on this issue in recent days? How to add web parts on List A form if List A has used unique permission at this moment? Thank you very much.
Regards,
Eric
