How does the caching work?

This plugin requires explicitly minimal setup time and no configuration at all. No coding, no configuration – install and activate, that’s all! Your website is now optimized and loading faster!

The WPCacheOn plugin has the ability to create two cached files. First is in plain HTML and the second file is gzipped (gzip level 9). Those static files are used to deliver content faster to your website visitors without any database lookups or gzipping because the files are already precompressed.

Stay tuned for new features!

What is WPCacheOn?

WPCacheOn speed-up page loading and improve website score in services like Pingdom and GTmetrix. WPCacheOn will remove any query strings from static resources like CSS & JavaScript files, enable GZIP compression (compress text, html, javascript, css, xml and others), add Vary: Accept-Encoding header and set expires caching (leverage browser caching). With our PreCache™ technology your website will be cached after the plugin is installed. This means that once WPCacheOn is installed your website already become faster with lower loading time and better results at GTMetrix and Pingdom.

Are there specific requirements for WPCacheOn to work?

The GZIP compression should be enabled in your web-server, no matter if it is Apache, LiteSpeed, NginX or another. If GZIP is not enabled you can ask your web hosting provider to enable it.

The .htaccess file in your WordPress instance root folder must have write permissions such as 644.

What to do if I get 500 Internal Server Error after plugin activation?

If you get “500 – Internal Server Error” after the plugin is activated, follow the steps below to easily return your website to working state:

(1) Login to your hosting account via FTP or File Manager. If you are not sure how to perform that, you can ask your hosting provider.
(2) Go to the WordPress installation folder also known as the root directory of your website.
(3) Rename the .htaccess file to .htaccess.deactivated. Then rename the .htaccess.wco file to .htaccess.

WPCacheOn is using many .htaccess rules related to different web server modules for optimizing the website performance. If some of the web server modules are not installed this will result in Internal Server Error. This is the most common and easy fix to this issue.

If this don’t resolve the issue, you can contact us or your web hosting provider for more in depth investigation.

This plugin helps me a lot to run my website smoothly. First time i see such a nice plugin where all are ready. Just download, install and activate the plugin. Get-Set-Go. Happy with WPCacheOn till date.

I just made a review of different cache plugins and was very curious about this one. I compared GMetrix results with Swift Performance Light and CacheOn did not have a good score for YSlow test (less than 80%). So I’m not impressed. But it works without problem on the test site and options (very little) are very convenient to check. Better than no cache plugin but I think other well known plugins will do a better job with proper configuration.
