problems since a few days

HI,
I am using restrict content by role since a few months. The plugin was working perfect. But now when I am creating a new site and select some role to restrict, cannot login to this new page even as admin. Also if I change the settings in a still existing page the same happens there.

I don’t know if it’s because I am running the plugin “My Private Site” parallel.
Maybe you have some idea to solve this problem.
