I have checked your site with default WooCommerce theme and see the same issue http://prntscr.com/gnh62i
Problem is related to Wordfence Security plugin. Check the plugin settings or contact plugin author about this issue because we provide support for issues related strictly to our theme or plugins that come bundled with our theme.
Default WP, WC plugin settings or questions related to third-party plugins are out of the scope of our support.
