Hi, Have you tried editing the permissions for that forum? It may be set to allow only certain user groups access.
You can modify the permissions of your forums by going into you Admin Panel=>General=>Forum=>Category & Forums... Scroll down to Forum Permissions Control and there you can modify all your forums permissions accordingly. I hope that helps some
