Modal no longer working

Hi,

The modal dialog used to work on my site until I updated to the latest version. Now it won’t display on any page. I’ve tried disabling all other plugins but no results there.

I’ve also tried setting the modal dialog in the post edit page, specifying a specific post ID, just leaving it blank to display on all pages and any other variation I could think of but it’s still not displaying.

The site (and page) I’m trying to get this to work is https://adriancrook.com/a-practical-free-to-play-game-economy-design-example/.

Any ideas?

Thanks.
