Purge Cache

All cache objects stored in both files and the database will be deleted. 

Along with default WP object cache and transients, cache from the following plugins will be purged: 

• W3 Total Cache
• WP Cache
• LiteSpeed Cache
• Endurance Page Cache
• SiteGround Optimizer
• WP Fastest Cache
• Swift Performance
• Hummingbird

WP Reset does not manually delete cache from these plugins, instead, it uses their own functions to do it. So, in order to clear cache from any of these plugins they have to be active.
