I have been trying out Google ReCAPTCHA on some Quforms across two different WordPress sites, and the ReCAPTCHA is sometimes not loading. The following error appears.
Note WP Rocket is running on both websites, combining JS files is turned on but Preload cache is turned off. Could this be further conflicts with caching? You have mentioned that you will be looking into caching on another post. Just providing more info for you as conflicts with caching must be a key thing to solve, with it being very common and such a big part of WordPress.
