Same issue here with both my live and staging site. Hope I can contribute to a solution.
It also says under Update: "UPDATE UNAVAILABLE! Please enter a valid license key to enable automatic updates."
I tried reactivating multiple times, with positive notification at first, but still can't update the plugin.
Also tried deactivating all plugins, same problem.
What's the issue here, and what are the exact steps to truly activate the license?
I've read somewhere that Meta Box checks the license key once per day.
So if I click activate, do I need to wait one day? Or do I need to take more steps the next day?
Or should I leave it completely blank and wait for one day, then reenter it and wait for another day? How does it go down? And should I delete the site first from the "active" list within my Meta Box account?
Cheers! 🙂
