Hi @asksj ,
did you use a solution from Full CMS Lightbox post after the update?
His post is very incomplete, the links are not working anymore.
I have to add the captions to my lightbox, so I followed his instruction and inserted “caption”: “Caption” into the code but it’s not rendering that element on the HTML preview. Do you maybe have any idea why is it happening?
EDIT
I tried again and the solution from that link works even after the update.
