I've had the same problem a year ago and you helped but the issue is back. Image descriptions (not Alt/Title) disappeared from under the pics in the galleries in samaralife.com (not every picture in every gallery has a description though).
I checked the files. Fancybox comment is deleted from the footer file in the Origin theme files, and the position of caption is changed to outside with opacity at 1, yet there are no descriptions anywhere but in the Manage your galleries pages in Dashboard.
I've updated the theme a few days ago and it might have some new files affecting the issue, but I could only change those you told me to last year. I am still on NGGallery 1.9 too.
