I created a new permission level for that role in wpForo

I created a new forum and gave acceess  only to that permission level

Now when users that have that role login they see a message they have no access because i set no access to the Registered role because i dont dant everyone to have access. Only paying members

What am I doing wrong? How can i give access only to that role and keep other registered members with no access??
