I have one issue.Lightbox script in general settings will not allow the option to change the PrettyPhoto, FancyBox and Nivo Lightbox. Only Swipebox works. Deactivated all plugins and can not find a solution. WordPress 3.7.1 sjruppel.com
Steve, the plugin options are JavaScript driven so I think there must be a JS error somewhere on the backend of your site. If you won;t be able to figure out that, please provide a temporary admin access for us.
Sorry Steve, but even after login I don’t see any gallery or single image links. I mean that I don’t see any elements on your site that Responsive Lightbox could work on.
