Comments not displaying

Hi

I’ve just installed WordPress, an older version I think, not the latest.

Comments have been enabled, not moderated as long as name and e-mail is input.

I’ve been left a comment on a post, but it’s not showing on the post page, I just see no comments.

I can see the comment when I go to manage/comments etc.

Can’t work out what’s going on.

Cheers
Darren
