Hello,
Today we upgraded confluence from version 6.0.6 to 6.13.2; after upgrade, we got the following license error:
License Inconsistency: Confluence support and upgrades for your current license have expired.
You'll need to supply a valid license key. Confluence can't start without this.
If you have a new license, please enter it on this page and restart.
But, we have licenses for both confluence and Comala Workflows for Confluence until October 2019.
Thanks,
Robert
