System error occurs when billboard actions are made

A system error occurs when a billboard request is performed if the system cannot start the Workflow task. By default, billboard workflows are configured with the Submit immediately check box enabled. This means that a Workflow task is started immediately when a request is made by a user. A system error results if a request occurs when the Workflow is paused. A system error can also occur if a request happens and the Workflow task has not been added to the job scheduler. To enable shift billboard requests, the Workflow task must be scheduled to run on a recurring basis in the job scheduler. Ensure that the Workflow task has been added to the job scheduler and that it is not paused.
