I'm Jérôme, the developper of Page Cache Ultimate.
I'm happy to announce that the module is now released with a zip compatible with Thirtybees, you can get it here: https://jpresta.com/en/prestashop-modules/1-ultimate-cache-page.html
Be aware that version 8 is much faster than previous versions thanks to a new caching system almost as fast as a static file.
