How to enable cache types?

Cache is a separate area of your hosting server, which is used to store web pages through browsers to speed up the load processes. To solve the issue with updates made on your website content the cache should be refreshed. Thus each time you make changes to your online store you need to refresh the cache to make them visible on the frontend.

How to Clear Cache in Magento 2?

Everyone looks for a solution that allows for fast and effortless cache deleting in Magento 2. Here are the simplest methods to clear cache. 

Option 1: Magento 2 Clear Cache via Admin Panel

• Navigate to the Admin Panel> System> Cache Management:

• Define the cache types that need to be refreshed;
• Tick the Cache Type blocks that are assigned Invalidated status or choose All if you don’t know what to refresh;
• Set Refresh action and click the Submit button:

• You can also use the ‘Flush Magento Cache’ and ‘Flush Cache Storage’ buttons directly.

What is the difference between flush Magento cache and Flush Cache Storage?

*‘Flush Magento Cache’: allows for refreshing cache you see in the backend and remove inner cache with Magento tag;

*‘Flush Cache Storage’: refreshes cache of all Magento stores sharing one cache storage (like Redis, magento Memcache), though based on different servers.

!If you run one of the cache storages together with Magento-based websites of other merchants, having refreshed it like that, you’ll clear their cache too!

Option 2: Magento Clear Cache via Command Line

Magento 2 allows you to clear cache manually via the command line. To clear Magento 2 cache manually you may need the next commands: 

• To enable the cache:

php bin/magento cache:enable

• To disable the cache:

php bin/magento cache:disable

• To flush the Magento 2 cache via command line:

php bin/magento cache:flush

• To clean the cache in the website:

php bin/magento cache:clean 

To clean particular cache types, you need to specify (comma-separated) the types, e.g.: config, layout, block_html, collections, reflection, db_ddl, eav, etc.

Full Page Cache

You can enable Full Page Cache option to enhance your website performance and speed up pages load:

• Navigate to Store> Configuration> Advanced> System> Full Page Cache and choose one of the options you need Built-In Cache or Varnish Cache:
