do i still need to td-speed-booster plugin if already have wp super cache plugin

Hello nhatkymua,

Yes, it’s reccomended to use the Wp Super Cache if you are using the TD Speed Booster. For more information about how you should make your website faster, please check the documentation from here -> https://forum.tagdiv.com/how-to-make-the-site-faster/ because there you will find all of the useful steps which have to be complete in order to achieve best theme results. If you are not aware of the steps which are needed to take in this case, please consider hiring a freelancer/developer to help you because we cannot provide speed optimization.

Thanks for your understanding!
