WP-Optimize bypasses the need to be logged-in

Hello,

I am currently working on an intranet-type site that serves information internally for a company. The theme i use is Anesta, that forces users to log onto the site via WordPress login. If they are not logged in, they are automatically redirected to the wordpress login page. Upon activation of WP-Optimize Cache, everybody could see all pages without the requirement to be logged in.

Is there a way to fix this? The plugin significantly increases the speed of the website but it needs to ensure that the user IS logged in.
