"There are no items in your cart" message is missing?

Have a look at your display.php page and on the last line it should say:

} else {
			$output .= "<span class='no_items'>".__("No items in your cart","SCABN")."</span>";

  		}
		$output .= "</div>";
		return $output;
	}

Just after $output .= "</td></tr></table></form>";

It could also be your text colors being the same as your background and as a result they vanish…

I don’t have a display.php page in my plugins folder…?

And the font color isn’t the issue, it isn’t printing anything at all – you can see there’s no gap between the title line and the horizontal divider: https://gilveyglass.com.

you can find display.php under “plugins\simple-cart-buy-now\classes” folder.
I dunno what it could be, have you tried adding a <br/> just before that last </div> ?

I don’t have a classes subfolder either?? What’s going on?

What version of SCABN do you have? The classes structure was added in 2.0.
