This issue drive me crazy for weeks, but I am not used to contact the support of the products I buy (my mistake) 😀

Finally, I contacted simultaneous the Elegant Themes and the WP Rocket support and they both give me the same solution about this f—— issue 😀

If your Divi website is Broken randomly using WP Rocket :

Just disable the performance options of your Divi Theme

Disable the static CSS file generation

(WP Rocket will works well anyway for your performance)

minification / concatenation divi Wp Rocket

Fix broken CSS for Divi & WP Rocket

If the problem persists, do not hesitate to try disabling the second setting (CSS minification / combination) also and using the WP Rocket minification / concatenation instead :

Basically, WP Rocket recommend to disable ALL performance settings of any theme in case of such issue ! 😉
