Photography theme opacity dropped to 0

The opacity on my blog page, Photography theme, dropped to 0 so now none of my blog posts are visible. All other pages re fine. How can I push the opacity on that one page back to 100?

Hello Bro!

You better share a link.
Or a screenshot.

Howdy, this is the blog page
It changed from visible to invisible sometime in the past few weeks (I haven’t checked that page for a while.) My developer says the CSS opacity is set to 0 on that page, but I dont know how to set it back to 100, and I have no idea why it would have set itself to 0. Thanks for any insight you can offer.
