I uploaded photos and changed the avatar photo, but they don't show up.
In chrome I see the broken image symbol, in firefox nothing.
When I copy the image url and paste in browser tab, I get a Server error 500.
In my ftp program I see the files in ow_userfiles/plugins/photo/
and ow_userfiles/plugins/base/avatars.
What setting do I need to correct (on server?) to show the images?
