Problem: I see error messages stating that the Toolset plugin cannot connect to toolset.com. Toolset needs to connect to its server to check for new releases and security updates.

Solution: Generate a new site key by unregistering the software first if necessary in wp-admin > Plugins > Add New > Commercial tab. Register the software again and click the "Get a key for this site" link to generate a key for the appropriate URL. Copy + paste the new key into the registration site key field. Click "Check for Updates" again to hide the error message.
