Since yesterday we're not able to create new entities (story, bug, task, epic) within the projects. we're used to creating these within the backlog view but it isn't working.
we get this message -We can't create this issue for you right now, it could be due to unsupported content you've entered into one or more of the issue fields. If this situation persists, contact your administrator as they'll be able to access more specific information in the log file.
and this - Some issue types are unavailable due to incompatible field configuration and/or workflow associations.SummaryRequired
We have not made any changes to fields or workflows.
