I am facing a interesting issue in SharePoint Online: when I view detail of a list item, it's created by field is showing blank.
This is how I see it:
What could be the possible reason? How can I find who created that item?
This happens to me when I have a list that allow anonymous users to add itens. So if the user was not authenticated and he can add itens the information of Created By
and Modified By
will not be shown by SharePoint.
Here is another post/thread on this site that talks about this... Users cant see 'Modified By' or 'Created By' (columns blank)
