Reauthorizing facebook application

I'm developing a facebook application and everything is going fine with log in and comments etc.

I came across the issue of 'reauthorizing' users. One of my users 'accidentally' pressed 'don't allow' when it asked them for access to their information and now they cannot sign in.

Does anyone know how I can reauthorize them?

Thanks in advance.

Edit: It turns out that once I officially published t开发者_如何学Gohe application the users' error disappeared. I'm pretty sure you aren't supposed to have work-in-progress published apps but that certainly solved my problem.

It should ask for permissions automatically. Try to tell him to do this:

1. Go to My account > Privacy settings (I don't know the exact text of the option because mine is in spanish).
2. Then, in the footer menu, select Applications and Web sites
3. Next to Applications that you use, click on Edit settings
4. Search your app and delete it.
5. Re-enter in your app and permissions dialog should appear.

As explained by manuelpedrera previously, after the user remove the application from their facebook account, he / she has to re-access your website and retry to login to your website using their facebook account. Once they choose to allow the permission, your app will again be added under their facebook account and everything should be back to normal. good luck mate :-)
