Question

I’m experiencing an error which wont let my page load.

Uncaught TypeError: Cannot read property ‘msie’ of undefined

The error in the console refer to this code:

if (jQuery.browser.msie)
    extra_px += 3;
                                                   // Fix Link Clicking on IE 7 and below versions
if (jQuery.browser.msie && Number($.browser.version) < 8) {
    span_text.css('cursor', 'pointer');
    span_text.click(function() {
        window.location = menu_item.parent().attr("href");
    });
}

The weird thing is that it suddenly happened, I didn’t change a thing. For reference, I’m using WordPress.

jQuery.browser was deprecated in version 1.3, and finally removed in
1.9.

As you can see in current version of jQuery, there is no $.browser property anymore.

Most probably it was moved to plugin as was stated in docs.

So if you use the very last version of jQuery, the undefined error is understandable.
