I need some help. On my website I have “Categories” and below that “Pages” and below that “Posts”.

My problem is that I cannot get the “Posts” to sort alphabetically. I have tried the suggestion above and it didn’t work for me. Maybe I was adding it in the wrong area.

Here is one of the pages:

The theme I am using is “Twenty Ten”

Thanks
