This plugin requires PHP 7 or higher and (optionally, for best performance) WordPress 5.8 or higher!

Lighthouse is a performance tuning plugin, removing lots of default WordPress behaviour, such as filters, actions, injected code, native code and third-party actions.

With Lighthouse, you save over $480 in over 10 hours of coding by a web developer, which you would need pay to do it for your website, or to purchase separate optimisation plugins.
