Hi everyone,
I had the same issue with my mobile hamburger menu not opening after enabling the Remove Unused CSS option in WP Rocket.
I fixed it by adding the following to the CSS safelist:
/wp-content/plugins/gp-premium/(.*).css
However, this excludes all GP Premium CSS from the “Unused CSS” feature in WP Rocket. So I was curious if anyone has been able to narrow it down to the exact class or ID that needs to be safelisted, rather than safelisting the entire GP-Premium CSS file? This is a tricky one!
Best regards,
Jesse
