Hmmm ... actually ... the problem may be even worse than that ...

If you try visiting that URL with your browser, you'll see that the page is blank and a "not found" error is returned.

So, whether that allow_url_fopen is set or not, you're still gonna get no useful data back.

If you want the functionality that that sidebox was giving at one time, you'll need to find another source for the data before you even bother considering the best method of reading and parsing the data for use.

For now I suggest turning off the sidebox: Admin->Tools->Layout Boxes Controller.
