Scrolled Trigger Box Appearance Problems After Update

The box was perfect (yellow default) prior to plug in update. After plug-in update, text was faded and could not be seen. I then change to different theme. Now the box does not look correct. You can see box appearance by going to my website and scrolling down to bottom: http://www.mobilewirx.com

Please help!

Thanks,
Dennis
