Buttons not showing up

I can’t get the buttons to show up at my site (it’s still being developed so it’s got a test url):
http://104.152.168.27/~signacom/

I’ve tried de-activating the other plugins and I’ve added this to my custom styles:
.woocommerce-page .product_meta{
display:block!important;
}

no luck.
Any ideas?

Thanks!
