WooCommerce.php has completely overran my content background color

So I’m super new at this and while doing all the layout and graphics for my friends company, he asked me to see if I could change up the site a little. All I want to do is add a woocommerce store.

The theme is a custom one that a company did for them and has since decided they didn’t want to handle smaller businesses. Now it all looks good but the content background color on all WC pages is transparent and it needs to be white.

I’ve tried a bunch of custom.css and style.css options but I think it must be overriden..somewhere.

You’ll see the product title is also misplaced, here is the Url.

Thanks for your help in advance, let me know what snippets I can show that might help.
