Pay with a like not revealing hidden information.

I have installed Pay With A Like and it seemed to work well when I had a designated url that was shared on facebook. When I removed that url so that the page that the Pay With A Like was on it stopped working properly.

Sometimes, depending on the browser, it will actually add the like to a facebook account, other times it wont. And no matter what browser i have tried it on its not revealing the hidden information.

The page that I have this on is at>>>>

any help would be greatly appreciated.
