            Here you can check the system status. Yellow status means that the site will work as expected on the front end but it may cause problems in wp-admin.
            <strong>Memory notice:</strong> - the theme is well tested with a limit of 40MB/request but plugins may require more, for example woocommerce requires 64MB.
