Warning: sprintf(): Too few arguments

Hi, I’m trying to install the required plugins for the HighEnd theme on my site everydaygeo.com. The plugins I am trying to install are the required/recommended ones:

* Visual Composer – Live Drag & Drop Page Builder
* Contact Form 7
* Essential Grid
* LayerSlider
* Revolution Slider

However, I receive the following error message:

Warning: sprintf(): Too few arguments in <path on my blog site> on line 154

Not sure how to turn this into a “Support Ticket” or make this a private conversation… Any assistance would be appreciated.
