I have a problem editing and creating new workflows with SharePoint Designer for SharePoint Online. The problem started to occur 2 days ago (The SharePoint configuration hasn't changed). The Designer seems to be working properly until I want to create/edit any workflows. Upon clicking the workflow a messeage is displayed:
"Unable to load workflow actions from the server. Please contact your server administrator."
- Reinstalling the designer and deleting the cache.
- Using another user to start the designer (as SharePoint Admim).
- Creating a new workflow (fails).
Workflows uploaded before the error are working fine.
Does anybody know about this problem or what I could try? Currently thinking about creating a ticket since I do not have access to ULS logs (SharePoint Online).
