[Plugin: Simple:Press] Permissions Not Working

Is anyone else having trouble getting the permissions to work properly in Simple:Press? I have always allowed guests to have full access to my forum but now I want to change it so you have to be a member to access the forums. I have set all of the forum permissions for the Gust usergroup to No Access but when I log out and test it as a guest, I can still have full access all of the forums and posts.

I have checked to make sure that the settings in the No Access permission are correct (none of the options are selected at all), and I deleted all cookies after logging off – but it looks like guests still have full access to my forums even though every forum shows that their permission is set to No Access.

Anyone else having this problem?
