I have a SharePoint Online Site Classic team site template. I also have 1 blogs site as subsite underneath it. On top level site i am using content query webpart to publish blog items from blogs subsite.
Now i am trying to assign users to add comments on the posts. To do that i went to blogs site --> Site Contents--> Comments--> Lists Settings-->Permissions for this list.
On that page i broke inheritance and assigned visitors group a contribute access.
When i did that xslt webpart on top level site bombed. It triggered following error.
The "XsltListViewWebPart" Web Part appears to be causing a problem. Unable to find the specified file.
I dont know why this is happening, I have implemented this in SharePoint 2013 onprem no problem. Why is Sp online acting the way it is.
Any way to mitigate this issue?
