Thank you, Djbaxter, Well, I don't understand either so I wanted to know whether it is a thing.
We received some critical comments from some security guy that out forum is not sufficiently secure. He refuses to explain further.
He said :
Index listing is enabled and ought to be disabled to prevent
information leakage
Directory listing is easy to disable under LiteSpeed. It's a
security issue. Why easily provide information to an attacker?
Is this related to user profiles being visible and users being contactable by non users from outsite via Xenforo?
LiteSpeed I understand is a faster alternative to Apache
