Great but please make some sanity checks

I think it’s great that you took the initiative to create a userfriendly (good for most) caching plugin. Tho, one thing that’s indeed very dangerous is the memcached/redis option. When running a server that doesnt have these functions installed, activating this feature causes the WP site to immediately 401 crash. The only way to recover the site is by modifying the DB, or manually deleting the plugin. Since this plugin is intended for novice users, this might lead to a lot of crashed websites.

It would be great if the plugin could add something to prevent this from happening.
