"uncaught Typeerror: Cannot Read Property 'open' Of Undefined" - After Calling ".start();" - Plupload

Using plupload, I get the following error when calling .start(). From this line: I am using RequireJS to handle the libary. Using latest version (v2.1.2). My code: How my script

Solution 1:

Turns out it is a problem with UA-Parser plugin. It thinks I am on Internet Explorer on Vista. But I am really on Chrome on OSX Yosemite.

This will in the end cause the function _getNativeXHR() (in Plupload) to mistaken me for being on Internet Explorer and this causes the crash.
