* Don’t touch anything in /var/cache!
* Sarah is the WP expert, and her email says it all better than I can - read it carefully.
* I would assume Proxy cache invalidator just adds headers to bust caches like varnish, but as Sarah said, it’s not going to be a cache like varnish that’s causing your problem.

In the meantime, if your droplet uses php-fpm (rather than mod-php) you might find restarting that service clears the cache rather than having to do a full server reboot.
