Is there a conflict between Rocket Loader and Wordpress 5.6/WP Job Manager?
We updated to Wordpress 5.6 which meant that job listings were not displayed. We de-activated Rocket Loader in Cloudflare and the issue seems to have resolved (although page load times are now much higher).
Rocket Loader isn’t compatible with all JS. If it’s breaking something, open a Support Ticket and let them know what’s not working. They can test Rocket Loader on your site without it being activated.
