@andrioslogos I’m positive you haven’t set up the plugin properly or didn’t configure it at all as stating “i doesen’t work” suggests you just activated it without applying any settings.
This is not a one-click solution that will magically speed up your pages. Even well-known plugins that are super user-friendly and have millions of downloads still have to be configured as each website is unique. I’d appreciate if you can at least update the rating as I believe it was out of frustration that you’ve activated the plugin on many websites you own and you lost time doing that. Note that I made the layout more user-friendly than it used to be and made some Pro features available in the Free version.
It would be great if you could share with us more about your experience.
Best wishes!
