child page doesn’t show up

What are you using to generate the page menu?

I’m justing wordpress. i’ve just been filling out the Page Attributes and selecting parent, child, etc.

What template tag is your current theme using to generate the page menu?

does that help? I’m not quite sure what the template tag is.

You need to look for wp_list_pages – probably in header.php. That said, I’m not sure your theme will display child Pages as it would have to display them in a dropdown menu.
