We have set up a popup in Hustle, which is designed to open when buttons / links with the CSS ID of #free-ebook are clicked.
The popup is launched in two places – from a panel half-way down the home page (which works) and from a footer widget (Sign up for a free ebook). The footer widget works on some pages, but it does not work on the invidual book pages
which use template single-book.php, or on individual blog posts e.g.
which use single.php. There is nothing untoward in the browser console. I can’t work out what the difference is between places where it works, and places where it doesn’t.
Maybe you will see something we’re missing.
