Calendar Not visible unless logged in

The calendar will not be displayed on our site unless a user is plugged in. I know exactly what line of code is causing the issue, but I’m not sure what to do to fix it. The site is also using Woo-Commerce and aMember. To get WooCommerce to work correctly, I needed to add the following filter

add_filter('woocommerce_prevent_admin_access', 'check_admin_access');

Which runs this funtion:

function check_admin_access( $redirect_to ) {	
	$user = wp_get_current_user();
	$admin_roles = array('administrator', 'chapter_president', 'shop_manager', 'editor');
	//$admin_roles = array('administrator', 'chapter_president', 'editor');
	if( is_array( $user->roles )) {
		foreach($admin_roles as $role) {
			if (in_array( $role, $user->roles ) ) {				
				return false;
			}
		}
	}
	return true;
}

Something in this function is causing your calendar to not display. The calendar will only display for users who have one of the four roles listed above.
