I searched the error and maybe I found the html button with link is not correct. Keep in mind the spec says this is not valid as buttons should not contain any interactive descendants. http://www.w3.org/TR/2011/WD-html5-20110525/the-button-element.html.
You must the HTML button within the link make: <button>text</button>
I’m testing the plugin on the website http://www.stative-test.de.
When I test your website http://www.readythemes.com/demo/?theme=Reviewginelite, the button also does not work.
