  • Zombie plugin

    I paid for the Pro version - and left a five star review here - years ago. But it was abandoned about eight years ago when the authors got another job. Installing a new site, this appeared in the list when I was adding plugins as 'updated' recently. Oooh, has it really? No, the latest version is still the 2017 one. Zombie.

  • dead project

    dead project, period. It's never been developed since 2017... cause the 170220 update was posted on Facebook in February 2017

  • Good product!

    I have used this product on a couple of websites I have built and have had positive results, however after a few days of operation, on one of the websites, the product would produce a visible text error on top of the home page of one of the websites I used it on. This was regardless of the way I configured it, and the cache had to be flushed to resume normal operation. This plugin also has paid versions that add some capability to an already good product. I eventually switched to a different product as my standard for commercial websites, but still believe this product to be one of the better cache plugins on WordPress.org. It is a good product, and I recommend downloading the latest free version and running it for a few days to determine compatibility with your specific website!

  • Super smooth plugin, A+

    Perfect for a site with static pages (e.g. with no user comments, etc), it generates html pages on the fly, super fast, good results in google speed test.

  • Für mich Leider nicht zu gebrauchen

    Funktioniert als "stand alone Anwendung" gut, also ohne andere Pugins. Eigentlich nicht das was ich mir von einem Cache Plug und einem "Pro Plug-In" erwartet hätte. Macht Probleme mit MonsterInsights Pro und dem blog2social Plug z.B. Was auch noch ein ganz großes Minus ist, es findet keine wirkliche Admin-Warnung statt, so als selbst-Test so zu sagen, ob das Plugin fehlerfrei läuft oder nicht.

  • Awesome Plugin but pity its been abandoned by Author

    Comet Cache is the most easiest to use and setup caching plugin which sped up many of my clients sites which were lagging real bad when none of the other caching solutions were working properly out of the box. Its such a pity that perhaps the best caching plugin for wordpress has been abandoned by its developers, i wish we could do something to help !
