Hello Long Nyguyen, i try to install new WPML updates for my site: lien caché via the plugins commercial tab in WordPress. When i register WPML it states that my site key is invalid. I have add the site key from WPML dashboard and checked if the domainname is correct (lien caché). Also when i check the WordPress status log, it states that updates is not possible due to invalid site key. Can you help?
