I'm not seeing the lightbox activate on thumbnails .... I think something may have been broken with the .0.10 merge into 1.1.
NOOOOOOoooooo............... :rip:
Added it back to this site ... issue is in display template right after if ($attachment['thumbnail']['has_thumb'])
it should use $attachment['thumbnail']['lightbox'] and not $attachment['thumbnail']['javascript']
Committed.
BTW: I'm keeping locally a branch with the merged code, one the release is done I'll use it to create the real merge commit for the development branch and push it.
