LiteSpeed Cache is the plugin that helps the website load faster. A cache is a mechanism that stores data in a way that makes it easier or faster to retrieve than the original source. A cache’s primary purpose is to speed up retrieval of web page resources, decreasing page load times.

As the title indicates this is the Pro (and paid) version of the main page builder we use for our projects. The Pro version gives you a lot more options to design your website exactly the way you want it to look and function.
