bullets don't display

Please post a link to your site.

Your bullets are already enabled but are being hidden because of lack of padding. Find this line in your child theme’s CSS:

ol, ul {
    list-style: disc outside none;
}

and add some padding so it looks like this:

ol, ul {
    list-style: disc outside none;
    padding-left:10px;
}

This will add padding to all your lists whether they have bullets or not so you may see some affects elsewhere. For more on CSS Lists read this:

You really should use a child theme. Otherwise if the theme updates you will lose all of your custom edits. It’s really not that hard and only takes a few minutes. Use the link that Andrew posted above.
