As a certified trainer for Salesforce, we use the Workbench for an exercise with students in the T&C DEV502 Integrations class, and as of late have been hitting an error:
We can't get the subscription to take hold, and we continue to get the same error. We've also IE, Firefox and Chrome, all with Cookies turned on - we get the failure 'no BAYEUX_BROWSER cookie present.'
According to Workbench version info, it should now be working past v25 and SFDC current version of Workbench is 25.0.7 that we use for our exercise.
Here is where the error shows:
