BUG - Not sure if you want to have a look at this or just point the finger at WP Rocket but content area modals do not work after the latest update if “Minify Javascript” is active in WP Rocket. Clicking on a previously-working content modal results in nothing, as if the button is not an active link.
WP Rocket has not had an update so your update broken this functionality. Previously, Minify Javascript worked fine with WP Rocket and content modals.
