Problem:
I received a message in my WP dashboard stating that my Toolset account was expired. I renewed the subscription and received email confirmation, but I don't know how to link the updated subscription to my site.
Solution:
Unregister Toolset from the site, then follow these steps: log in to toolset.com, go to "WordPress Dashboard > Plugins > Add New > Commercial (Tab)," click "Register Toolset," get a site key, and paste it into the "Site Key" input box. Click "OK."
