Sorry, it’s a bug in the code, if you cant modify the php you will have to uninstall the plugin and install the previous version until W3TC release a fixed version

Might be same error I just found in Util_Environment.php in function is_w3tc_pro

PHP Fatal error:  Call to a member function get_string() on array in /var/www/html/wp-content/plugins/w3-total-cache/Util_Environment.php on line 1042

CDN Engine is passing config as an array instead of an object

change function

	static public function is_w3tc_pro( $config = null ) {
		$result = $config->get_string( 'plugin.type' ) == 'pro' ||
			$config->get_string( 'plugin.type' ) == 'pro_dev' ||
			Util_Environment::is_w3tc_enterprise( $config ) ||
			( defined( 'W3TC_PRO' ) && W3TC_PRO );

		return $result;
	}

in my case i dont have pro version so changed function too

	static public function is_w3tc_pro( $config = null ) {
		return false;
	}
