Module content_access

Please help, I need professional assistance. It seems like a trivial issue, but I haven't been able to figure it out for four days. I decided to create a page for VIP users in Drupal 7, installed content_access, created a content type, and set permissions only for VIPs. I created the page, but... when I log in as a user, I can still access the page. What did I do wrong? I've searched the entire internet and couldn't find anything. Maybe I also need to change something in the user permissions? Please advise???
