I upgraded to the recent 2.0.59 update but still it did not resolve the problem. Anyone have any ideas?
Thanks to Cais at Photocrati Support, I have this resolved.
The problem was related to the “Add Hidden Images” feature. Under Dashboard > Gallery > Gallery Settings > NextGen Basic Thumbnails, the “Add Hidden Images” option was set to “Yes”, so I changed it to “No” there… and also changed it to “No” on every gallery on this site, and IT WORKS!
According to Cais, most people turn on the “Add Hidden Images” option so that all images in a gallery are shown in the Lightbox when there are multiple pages for the gallery. The “Add Hidden Images” option has a few quirks and the templates currently bundled with NextGEN Gallery are leftovers from NextGEN Legacy (pre-1.19.13) and do not honor many of the ATP options so they need to be used with care.
I hope this helps someone out there with the same problem.
