I cant set the order of the replies, instead of the replies the last posts lists show the topics order.
Maybe is waiting for new posts to show?
What do you mean saying "the last post list"? Please specify where is that last post list (in topics, in recent posts page, in widgets...)?
recent posts sorry
When i let 0 shows is like before, shows all posts from a topic.
when i set the limit to 1 or 2 it shows instead the posts order, the topics order.
