I'm checking the patron file upload with Plack, and seeing something odd; this may or may not be Plack-related. First, I set the patronimages & EnableBorrowerFiles sys prefs to Allow/Do. Here's the oddity I've run into so far (the other one went away while writing the bug report):
When I can finally get the Files tab up, the system says the patron has no files attached -- even though I've uploaded 2 files already. But if I upload another file, the now three attached files display, but if I click away from the files area, and come back, the system says the patron has no files attached, yet again.
The borrower I was working with: http://test-intra.plack.bywatersolutions.com/cgi-bin/koha/members/files.pl?borrowernumber=102
I can't reproduce it, everything around upload patron files works as expected for me... So I'm closing it. If you think it's still valid, please reopen.
