    In our LearnPress environment, we are actively using LayerSlider for presenting workflow steps and processes. However, LayerSlider seems to be getting into conflict with other LearnPress JS, disabling scrolling on the course pages. Here's the console error:

    main.min.js?ver=3.3.6:121 Uncaught TypeError: Cannot read property 'greensock' of undefined
        at Function.<anonymous> (main.min.js?ver=3.3.6:121)
        at q.check (greensock.js?ver=1.19.0:20)
        at new q (greensock.js?ver=1.19.0:20)
        at a._gsDefine (greensock.js?ver=1.19.0:20)

        at HTMLDocument.<anonymous> (custom-script-v2.js?ver=3.3.6:1453)
        at i (jquery.js?ver=1.12.4:2)
        at Object.fireWith [as resolveWith] (jquery.js?ver=1.12.4:2)
        at Function.ready (jquery.js?ver=1.12.4:2)
        at HTMLDocument.K (jquery.js?ver=1.12.4:2)

    Disabling the LayerSlider plugin makes LearnPress and scrolling fully work again. Is there a workaround or a software fix we could apply ourselves until the bug is resolved?


    Thanks for your help!

    Hello again,

    The problem is generated by your plugin. It loads an extra instance of Greensock, but does not have built-in sandboxing for it, so it conflicts with LayerSlider as it also loads one.

    You could try to use the Use GreenSock (GSAP) sandboxing option in the Advanced tab of LayerSlider. We've implemented it for issues like this.
