Though this article doesn't not belong to this category, but I have posted thinking that may be someone might have faced the same issue and can put some light on this.
I have created a facebook app for Nokia using QML. The app was running fine till day before yesterday, but from yesterday I am not able to loggin to the app.
When I start the app I get the login screen with the username and password. when I put the user name and the password it doesn't come up the permission page, but gives me some error message
"This page contains the following errors
error on line 3 at column 417: Expected '#' or '[a-z A-Z]' but got '&'
Below is a rendering of the page up the the first error"
I am using the url "https://graph.facebook.com/oauth/access_token?client_id=YOUR_APP_ID&redirect_uri=YOUR_URL&client_secret=YOUR_APP_SECRET&code=THE_CODE_FROM_ABOVE"
Please let me know if anyone facing the same issue.
