[Plugin: WP Super Popup] it doesn't pop-up, but I see script injected.

Hi!

Finally promising pop-up plugin, everything I looked up doesn’t work with wp-cache.

I’m trying to test pop-up here: https://www.sandrophoto.com/digital-photography-site-map/

I see code in the page, but after 2 seconds I don’t see anything. As I read somewhere on the forums here, it could be double jquery file causing conflict? Well I cannot remove this, because my theme runs on that. I don’t know how to get around this problem. Can I change pop-up plugin to use already included jquery file?

thanks!
