Show first post in index

I changed in my wp-admin that only 1 post should be visible. That works.

But how can I show the comments???

By default WP is not programmed to do that.
Search for exactly what you are asking for: “comments on index”

Damn, that I didn’t see that :p
Thanks, this did the trick:

I often received complain like that. To let you show the comments as people go on it is actually not a difficult task. so just visit the link to show how should it be done.
