This error means that the user's Site Role doesn't allow them to Bypass workflow, but there isn't an applicable workflow available for the type of action they're taking.
Here are some things to check:
- Edit the appropriate Workflow Definition and ensure the user's group is selected in the Groups field. Only groups selected there will be permitted to submit assets to that workflow.
- Ensure there's an appropriate workflow type for the action the user is taking. For example, to delete a page, there must be a Workflow Definition with the type "Delete" applied to or inherited by the asset's parent folder.
- If the user should be able to skip workflow, edit the appropriate Site Role to enable the Bypass workflow ability.
For more information on creating and applying workflow, please see the Workflows article in the Cascade CMS knowledge base.
