I get this all the time now, it seems. I go back to a site I did previously, same issue.. It seems like the license isn’t associated with the URL, but it is. Of course, none of the plugins that come with X will update either.
Updating Theme X (1/1)
An error occurred while updating X: Update package not available.
Forget this. I got it. Did I miss where this is spelled out?
If Settings>General>Site Address is Not Equal to the URL associated with the Envato license key in X, it won’t work. However, When you do change the two to match, you still need to revoke the existing license in X addon and re-input the key.
It is written somewhere, right? I likely just overlooked it.
