Question

There is some unknown problem with my facebook app running on heroku

Problem is now something with the access token. Im not sure what
It seems like something in the app corrupts my access token. Cause when I attempt to login to the app, and then use the explorer it says that im either logged out or the acces token is expired. but if I debug it, it says its valid for 2 more hours.
Also, the page fails to reload after I have logged in.

Aparently the site keeps reloading.. and updating over and over. This stops when logged in on the page

The error seems to have occured recently.. Didn’t have it last week. Im guessing the problem would lie somewhere here, but I can’t find it.
If you see anything that could give a problem please hint it out. Thanks
