The ajax search doesn’t start when typing a querie in the search bar.
This only happens on the FRONT end (customer facing). It does work when logged in.
I found that the compatibility issue is with WP Rocket.
Thank you for the details!
Unfortunately I am getting a firewall access denied error message, when trying to open the website: https://i.imgur.com/ErYMeAp.png
It was actually a known issue yet – party caused by WP Rocket. They have an aggressive “defer” script feature, and it detects things, which it should not detect. We added a “hack” to our new plugin release to address that. We are about to release it in a few hours – but I installed it for you. Once your clear your site cache everything should be just fine.
