Error 404: Non-Existent PNGs in wp-custom-css-admin-styles.css

Hello plugin authors! I rated your plugin 5 stars. Thank you for your work.

Just one note: I ran our website through a Broken Links Checker tool and it reports 7 not-found resources.

For reference, here are the resources it failed to pull. My only concern with this, other than being a perfectionist and not liking any broken resources, is that it’s increasing page load time as the browser spends a little time trying to find a resource that’s not there. The issue may be a quick-fix by removing these references from the css file?

Thanks again for your plugin!
