Works with WP Fastest Cache

I have always used Easy Fancybox for single image popups but after upgrading to the paid version of WP Fastest Cache, it would not work.

No amount of JS exclusions would fix it. So I hunted for a replacement and found this plugin.

It worked straight out of the box. A couple of tweaks and everything is perfect. Highly recommend if you need full caching for your site.

dont work

ну что сказать – просто не работает (ссылки все проставлены, настройки задрочены туда-обратно и по дефолту), зря время не тратьте

Just what I needed

Works perfectly out of the box. I was scratching my head on how to integrate the original Lightbox 2 into WordPress because the original plugin no longer works properly. But then came across this one and it works perfectly. Thank you for developing the plugin!

Works perfectly out-of-the-box

Works perfectly out-of-the-box for me on WP 4.9. I download the file, unpacked it, uploaded the simple-lightbox folder to my server, enabled the plugin in WP Admin and it worked immediately. Kudos to the author for making a plugin that works perfectly out-of-the-box. Thank you!

Must-Have Plugin

This is one of my ‘Must-Have’ plugin!.
It is very easy to use and comes just ‘Out-of-the-Box’.
Simple Lightbox is clean, simple and just perfect for common use of Lightboxes.
