Flush The Cache

In order to purge out-of-date items from the cache, you can clean or flush cache types:

• Cleaning a cache type deletes all items from enabled Magento cache types only. In other words, this option does not affect other processes or applications because it only cleans the cache used by Magento. Disabled cache types are not cleaned.
• Flushing a cache type purges the cache storage, which might affect other processes applications that are using the same storage.

Flush cache types if you’ve already tried cleaning the cache and you still have unresolved issues.
You can flush the Cache using The Web Interface

Flushing all cache types:

1. Open the Administration panel and click on “System-> Tools-> Cache Management”.
2. Select all cache types and “Refresh” action in the drop down box located on the top left margin.
3. Click both buttons “Flush Magento Cache” and “Flush Cache Storage”.
