dfactory,
First of all, thanks for this nice plugin.
After installing this plugin recently, and wordpress 3.8 shortly after, captions of images in galleries disappeared. Today I spent most of the day trying to figure out what went wrong.
Many suggestions I found, among which this one, which I tried:
http://wordpress.org/support/topic/caption-text-instead-of-image-name-in-swipebox
It didn’t give me the result I was hoping for. Adding image captions only caused my gallery-images (galleries) to have captions on my pages or posts – which doesn’t always look so great. I also noticed this issue has been mentioned before in quite a few topics on this forum.
As a coding dummy I found an alternative solution, which was downgrading once again to WP 3.6, where I came from. I’m not sure whether this issue should be considered to be caused by WP or Resposive Lightbox, I’m only hoping a solution is found so they keep playing nicely together.
Anyways, thanks for this pretty plugin. I’m hoping this issue will be solved somewhere in the future, or a better solution for dummies will be offered :).
