You have the right idea! You can add an image to the classic editor like normal, and set it to link to media file, and it will open in the lightobx. And it is working on your site – the image is opening in the lightbox.
But I do also see the ‘double lightbox’ problem on your site. One of them is fancybox – from our plugin. The other (I think) is magnific popup. That’s not from our plugin, though. It’s likely it is being provided as a lightbox either by the theme, or by another gallery / lightbox plugin. You’ll need to figure out what is providing that, and disable it. Whether it is a theme or plugin, it almost certainly has a setting to disable the lightbox.
Okay, I did some digging and used Firefox’s “Inspect” and saw the problem. (don’t know why I didn’t think of that before). It was a lightbox provided by OceanWP (The theme I use), but I was able to disable it via the functions.php file.
So now it’s only showing 1 image instead of two! Just firelight lightbox.
Thank you!
Great to hear! Thanks for the follow up.
