If I use my Mobile Browser internet to go on my website, and log in through the Facebook login, everything works well..

but I created an free Mobile App with www.appsgeyser.com ( Free App maker with website url. ). It create a mobile app icon in your phone that when you click it it link you to the website..

But, if I try to Log in with Facebook. it doesnt work. Blank page. Freeze. same think if i try to like something.

Please, anyone here know the issue?
