Magento uses a caching system to assist your site in running faster. Caches are great because everyone likes a speedy website. However, if you change details within your website like your products, website files like themes are extensions, you will need to clear the cache to see the latest changes.
Best Practices for Caching:
- Always flush cache when installing/removing extensions
- Flush cache when installing Magento Commerce
- Flush cache after upgrading from one version of Open Source Commerce to another
- When flushing caches, take into account the type of cache and the schedule. It is best to flush cache during non-peak times where not many customers are accessing the site. If cache clearing is done during peak times, this may result in high load on the Admin which will cause the website to be down until caching is completed.
