Hi Clairese,
I'm very sorry that you had a bad experience using WP Rocket.
However, we have a support to help all our customers configuring WP Rocket and resolving issues they could have with.
I would be very glad to personally help you, simply open a ticket here : http://wp-rocket.me/support/

That's a best and easiest way to solve your issue, compare to a comment on a blog post published 9 months ago :)
