Hello,

1. I suggest you read this info about Object caching from official WP Rocket documentation: https://wp-rocket.me/wordpress-cache/object-caching/#section-3

2. In our article we have described on how to adjust the CDN and integrate it into the WP Rocket plugin, please recheck it here: https://xtemos.com/wordpress-performance-optimization-the-ultimate-guide-in-2021/#Step_5

3. If you send me access to the site, I can investigate that issue with the speed, also, please confirm the permission for plugins deactivation, and switch to the parent/default theme. You would better make the full backup of your site.

4. Yep, the “Combine CSS” option has been removed from Wp Rocket, but you can do without it. Starting from WoodMart 7.0 you can enable the “WP Rocket delay JS exclusions” option in Theme Settings -> Performance -> Plugins (https://prnt.sc/ImFGamnkvefk). Thus the “Combine js” option can be activated.

5. Nope, you can use our “WP Rocket delay JS exclusions” option from Theme Settings so it populates that list (https://prnt.sc/cAK1K_IN3kU6) automatically

Kind Regards
