I’m having a similar issue:
Uncaught ReferenceError: STX is not defined
at transitionSlider.webgl.min.js?ver=2.20.3:6″
Uncaught TypeError: $(…).transitionSlider is not a function
at HTMLDivElement.<anonymous> (embed.js?ver=2.20.3:6)
at Function.each (jquery.js:29)
at HTMLDocument.<anonymous> (embed.js?ver=2.20.3:1)
at mightThrow (jquery.js:251)
at process (jquery.js:253)`
