Hi,
Photonic gallery was working great for me until I upgraded to WP4 (at least I think that is the root of the problem). Now it doesn’t show the flickr galleries at all, and just shows photos that have been added to the post for other purposes out of place.
I’ve played around with the embed code a few times to try and get it to work, but nothing does. The last one I tried was this:
[gallery type='flickr' user_id='XXXXX@XX' gallery_id='XXXXXXXX']
If there aren’t any solutions, I will probably try and revert to the older version of wordpress.
