Really odd- and I can’t replicate. The only difference is the url you use for the Member Photos ‘URL to Photos Folder’?
Hrm- looking at the code, if you switch it back to not force https, does it display logged in? Looking at the code- I suspect the logged in difference may be due to ‘$this->EE->session->userdata(‘display_photos’) == ‘n’’ - which should be determined on an individual level based on their settings for ‘Display member avatars in entries’ in your ‘My Account’ settings.
