Tell us what you are trying to do? The WPML asking for the site key. We had a staging hidden link and I registered that as our page when bought WPML. Now, when we have moved it to production hidden link it is asking they key and I can not made the plug-in updates. How I can change/get new key for production?
Is there any documentation that you are following?
Heh, when I clicked the link in WP, I actually end up the page where was the key for both the staging and production! Weird since when I was here on the page, I just saw the key for the staging. So, all good.
