This article will go over what the cache is, when you may need to refresh it, and provide a step-by-step guide on how to do so in the Magento 2 Admin Panel.


What is the cache?

You may be wondering why you need to refresh the cache and what it actually is doing. The system stores a copy of commonly used data ("the cache") for faster load times and if you make a change to a setting or update a content block, the site needs to adjust those copies.

When do I need to refresh it?

Many times after making a setting or design change, you will see the following notice at the top of the admin panel:

One or more of the Cache Types are invalidated: Configuration, Page Cache. Please go to Cache Management and refresh cache types.

When you see this message, you will want to refresh the cache.

The notice didn't show, but I'm still not seeing my changes.

Whenever you are not seeing your changes, the first thing you will want to do is refresh the cache. If you still do not see it after doing so, let us know and we can take a look.
