You nailed it, Duane . . . many thanks.
I went to Admin>Settings>Features>Files>Permissions, then selected "Subscribers can view and upload".?
Then I did the same for Photos.
Somehow those switches were reset about three days ago.? I don't know how that happened because members could upload files and photos before the beta testing began.? And I find no record of any such settings change under Activity.? No problem now that I know how to make the fix.??
Thanks a bunch for pointing me in the right direction!
