All caching plugins break Posts pages?

Been using Litespeed for years without a hitch.

On latest Generatepress, Elementor, WP versions

Now, with any caching/optimization plugin I use (W3, Autoptimize, Litespeed) everything works fine except the posts pages:

Live example: https://lagosnomads.com/guide-camper-van-rentals-algarve/

Happens on both my sites – have tried disabling most plugins and still no bueno. Any help would be hugely appreciated! <3

Thanks
