Error: Session exists already

The "License key validation failed: Session exists already" error can happen when you are using a developer license key from two different sessions at the same time. This can mean that:

• Two different people are using the same license.
• 1 person is using the same license in two different machines simultaneously.
• 1 person is using the same license in two different browsers simultaneously.

Please see section on Developer license](/6.1.2/licenses/developer-licenses/#error-license-key-validation-failed-session-exists-already) for more details and ways to get around this.
