My site http://www.laatusuklaa.fi would require updating to current WooCommerce 3 version and also an update to the Royal theme and all that it requires. I remember you having such a service (paid) but I can’t find it anymore.
Site URL: hidden Theme version: 2.8.1486309491 WooCommerce version: 2.6.14
The latest theme version (22.214.171.124) is compatible with WooCommerce v3.0.4, but the new theme version will be compatible with the latest WC version. Maybe, if you don’t face critical errors in work of your site, it would be better wait for the theme update and then update WC and Royal to latest version together.
Please contact us then and we will help you with the update.
