Before you install and use this plugin, please read the following notices carefully.

  • Logged-in users will not trigger the caching processes.

  1. Upload the plugin files to the /wp-content/plugins/cache-master directory, or install the plugin through the WordPress plugins screen directly.
  2. Activate the plugin through the ‚Plugins‘ screen in WordPress.
  3. Go to the Cache Master menu in Plugins and set your options.


Should I disable other cache plugins?

Cache Master caches full webpages to static HTML files so that it is better to disable other similar cache plugins that do the same thing. It’s okay to work with the object cache plugin together.

How do I know whether or not the caching is working?

Things to be aware of, the logged-in users will not trigger the caching processes. Please use incognito mode or another browser to revisit the same webpage, and then you can check the cache status in one of the following ways:

  • View the source code of the webpage to check the debug message as the screenshot (L)
  • Turn on the benchmark information in the footer section, as the screenshot (K), and you can see the cache status there.

If there is no debug message in the source code or the cache status always shows No, it is probably a plugin conflicting with Cache Master, causing it not working.

This cache assigned with memcached loaded websites to server memory, which if you keyed in a domain, a different website than the URL typed in came up. We installed it on five WordPress builds on the same server and each typed domain loaded a different site than what was typed. The admin access worked fine, the website build was still in place, however, the cache convoluted the websites left in memory. Needless to say, we dumped this plugin quickly. Two stars for a great concept. Caveat emptor.

Удобный, шустрый, так быстро кешировать еще ни один плагин не может. Разработчику огромное спасибо! Так держать и не прекращать дальнейшую поддержку и обновления. Хотелось бы, что бы плагин работал не только на новых выпусках WordPress и PHP, но и на старых тоже. Не понятно почему я его раньше не нашел. ------------------------------------------------------- Convenient, smart, no plugin can cache so quickly. Many thanks to the developer! So do not stop further support and updates. I would like the plugin to work not only on newer WordPress and PHP releases, but on old ones too. It’s not clear why I didn’t find it earlier.
