You will need to have the LiteMage Cache plugin for Magento installed and running.
How to clear the cache
Here are the steps you need to take to clear the cache that LiteSpeed is storing for your WordPress website.
- Log in to your Magento website.
- Click on System in the left sidebar, then Cache Management.
- Click Flush Magento Cache to purge the LiteMage cache.
You can further purge your cache by clicking Flush Cache Storage – however, we strongly recommend that you take a backup before using this option, as it may interfere with other applications or plugins using these files.
