Android and PHP high scores

I am using a hacked-up version of the highscore script by Lemo Dev in the asset store here: It works great... Except when compiled to Android.

When I am in the Unity Editor, it pulls up the high scores from my hosting with no problem and minimal delay. But when compiled to apk and installed on my Galaxy SII, even on WiFi, my device will never pull up the high scores. I checked my player settings, and I have Internet access set to "required". I even have PlayHaven integration on another app it will pull up the Placeholder ad with no problem.

Is there a problem with Android and PHP that I do not know about?
