Hopefully this will help someone, but I just had this issue. A couple things to check are: 1) can you find the php statement that goes something like this ‘<?php wp_list_pages(‘depth=1&title_li=<h2>Pages</h2>’); ?>’? If so, you can change the ‘depth=1’ to whatever. 1 means only one level and no sub pages. 2 means second level nav.
But thanks to the author of autumn-almanac for enlightening me, I found out that the reason I was unable to edit that above php statement and see any changes is that once you add widgets to the sidebars (at least in this template – I don’t know if it is true for all), you can’t edit the php.
I solved the problem by editing my page level statement first, and then I added the widgets afterward.
