Hi, @stovberpv
I’m sorry if you were confused. Our page in the Plugin Directory clearly states:
REQUIREMENTS
General Features may be used by anyone with any web server (LiteSpeed, Apache, NGiNX, etc.).
LiteSpeed Exclusive Features require OpenLiteSpeed, commercial LiteSpeed products, LiteSpeed-powered hosting, or the new QUIC.cloud CDN, now in beta.
And then it goes on to list which features are “General” and which are “LiteSpeed Exclusive.”
Perhaps there is an inconsistency in the translation?
In a nutshell: the plugin’s optimization features can be used by anyone. The caching features require a LiteSpeed product (some of which are available for free, by the way). I hope this clears things up.
