I think there must me something wrong with the "Role Manager" plugin. Clearly, when you enable "Publish Posts" you would expect the user to be able to publish posts.
The only way seems to be to also give permission to "Edit Posts", then the user can post. I am deeply mystified. Is there another setting that is in conflict with Role Manager?
This is the last hurdle for me, but I'm stuck until it's solved...
Anyone have a clue???
