The license could not be verified: License Certificate has expired!

Symptoms

Confluence is presenting the following error message in the dashboard and/or on some pages:

The license could not be verified: License Certificate has expired!

Cause 

While the error appears to suggest that the Confluence license is expired, it may have actually been generated from another Appfire app that is currently installed in your Confluence instance.
For example, the Scaffolding app may generate this message.

But the message could also be related to a different app, for example, the Visibility app.

Resolution

Check the license status for the add-ons by going to Confluence Admin > Manage Add-ons and check for possible expired licenses.

If you have an expired license for any Appfire app, you may renew your license by visiting the Atlassian Marketplace.
