I struggled for hours with the new role settings. Especially in metacourses I could not set the rights for the news forum according to my wished. Very frequently I used the "Login As" feature to check my new role settings.
Now I found out that not the role settings are the problem, but the "Login As" feature itself.
- Logoff / logon after each change in role settings.
- Do not use "Login As" to check the new settings; use some dummy accounts in stead.
