Hello ikkir,
Please check the following topic here -> Notice that the speed booster is an optional plugin which can be activated in the same way as you install a new plugin.
The Speed Booster works only with the tested plugins. If you use other plugins, it will be automatically disabled, and I suggest to check this first in System Status. However there is a workaround to make it also work with other plugins, you can read more here – https://forum.tagdiv.com/topic/speed-booster-not-compatible-with-vaultpress/
Unfortunately, the time doesn’t allow us to provide any custom and optimization services. We provide support only for the theme related issues based on Envato support policy – https://themeforest.net/page/item_support_policy I suggest to get someone to help you if you want to optimize your site.
Thanks for your understanding!
