Missing updated

Hello,

I have errors “missing updated” and “Missing author”
“Missing author” I found how to fix – I put this code on every page:

<span class=”vcard author”>
<span class=”fn”> © Steampunk BDSM</span>
</span></span></p>

But I can’t find how to fix “missing updated”.
I use Boutique child theme.

The page I need help with: [log in to see the link]
