I updated my forum from 4.0.1 suite to 4.0.2 level 1 suite last night. After that, I realized that the registered users can't view the sections and categories when they click on the links in the left menu bar. I looked around in the control panel and I found Permissions under vBulletin CMS and activated the permission for the registered users, but still they can't access to that. Could anyone let me know please, where the actual settings are located for that in the control panel?
