Have they come again since?? Double check the setting for the guest group by clicking Edit Permissions or Set Permissions next to the usergroup on the permissions for that forum.
Hello and thank you for your answer. I'll do that but the problem exists!
Ok, can you PM me admin account details?? I'll check all the permissions for you.
Next time please post the link of that visitor here and don't delete it yet.
