BUG: Upfront gallery lightbox

NGINX, MULTISITE, SUBFOLDER, AMAZON s3 cloudfront setup for media, UPFRONT->PANINO

for at least the last 2 versions adding an image and then setting it to a lightbox...fails to add the href needed for the lightbox.

Used to work...but now broken in at least the last 2 versions.

Thoughts on a solution? Thanks
