I am having a bug in my “pop up” boxes.

For example at https://www.oneblushingbride.net/products/diy-cathedral-length-draped-wedding-cape-pattern-pdf-tutorial?_pos=2&_sid=cc62bd4b0&_ss=r) work, when you click on “Which Style Should I pick? Pattern vs Video Tutorial vs Complete Material Kit?” (the green text), then the pop up page is supposed to be https://www.oneblushingbride.net/pages/diy-pattern-video-kit-landing-page). Instead, it is showing up blank.

For reference, below is what it looks like when I click the green text for my patterns.

How do I change this?

Have you had any luck with this? my pop up just has a blank black box
