Incompatible with InfiniteWP?

I tried to add my own site, which is running Cerber’s latest version, and Infinite WP (free offering) threw me a PHP Fatal Error Message:

PHP Fatal error occurred: Uncaught Error: Call to undefined function cerber_is_admin_page() in /home/—/—/—/wp-content/plugins/wp-cerber/settings.php:65
