Caching can be a very powerful tool to make your WordPress site load faster and handle lots of traffic. However, most caching plugins come with tons of features that can easily confuse a user who is not actually a developer. In this article, I will show you the easiest way to enable caching in WordPress so you can run your site efficiently without configuring any complicated settings.
Caching Configuration in WordPress
1. First, you need to Install and activate the Simple Cache plugin: https://wordpress.org/plugins/simple-cache/. This is one of the easiest plugins to configure caching.
2. Upon activation you will see a notice to turn on caching. If not you can always do it by navigating to the settings (Settings -> Simple Cache).
3. Page compression will be disabled by default. You should turn it on unless you see an issue on the front end.
4. There is an advanced option that you can enable on the top right corner of the screen. When this option is enabled Simple Cache shows more advanced options like Object Cache (Memcache/Redis) and Gzip Compression.
5. You may not have Memcache or Redis extensions set up on your server. But you can enable gzip compression to make your pages gzip compressed at the PHP level. Please note that many hosts set up gzip compression in Apache or nginx.
That’s it! Your website is now fully configured to use caching. If you don’t see the updated content after making some changes on the front end, feel free to delete all cache by clicking on the “Purge Cache” button.
