I am not sure if this happened with some earlier betas, but a site that had lightbox shortcodes working is now not showing them. They were showing videos.
The lightbox gets fired-up, but it contains nothing now.
This is the complete code:
<a class="ltbx-video" href="#" data-options="thumbnail: '#', width: 1080, height: 608">
<img src="#" class="ltbxvid">
</a>
[lightbox selector=".ltbx-video"]
