This has absolutely nothing to do with versions.

I had this code and got the same error:

$("#consoleBtn").click(function(){
    $("#consolePanel").toggle("display", {  from : { display: "block" }, to : { display: "none" } });
});

The problem was the arguments I passed to the toggle function. So I changed to:

$("#consoleBtn").click(function(){
    $("#consolePanel").toggle();
});

So be mindful of the arguments passed to your function when calling jQuery-api. Hope this helps.
