How to clear the cache in WordPress

WordPress does not have a built-in caching mechanism. However, many people use a caching plugin to help improve performance.

When caching is enabled, some types of changes (such as theme modifications) do not appear immediately. This article discusses how to clear the cache so you can be certain you are viewing the most recent version of your site.

Note: Before you try to clear the WordPress cache, make sure your own web browser cache is not storing outdated content.
