I saw another issue where methods being called IN the init function were causing this Uncaught Error. Although, not a permanent fix, but a fix nonetheless, wrapping the called method in a setTimeout(method, 0) works.

I’m guessing it’s just the timing of the init call that’s just calling slick methods before everything is ACTUALLY initialized, and to wrap the function in a setTimeout was enough of a delay to resolve the issue.

@sookcha the version used in the original issue is 1.8.1 (in the jsfiddle), where you are using 1.3.13 in your 09/04/2017 response. I hardly call that a solution when you are regressing the version.

I am also having the same issue, where I call the initial slick options, but my problems start after I call the slick init.
