Hey there,
Quite the awesome idea but I can’t seem to get it to work when I change the API url to the correct path on my own server.

I did some investigation and found that if I print_r($raw_response); after line 44 in the test-plugin-update.php file, which is the activated plugin, I’m getting an error on line 41 of the index.php file in the api folder. The error is as follows:

[body] =>
Warning:  array_shift() [function.array-shift]: The argument should be an array in /home/ivannova/public_html/demo/wpdev/api/index.php on line 41
O:8:"stdClass":1:{s:4:"slug";N;}

Any ideas would be welcome. Thanks!
