XF 1.1 Facebook Integration Passed but has some problems.

[Etchel]

So I integrated Facebook on my Website. Everything is okay. It passed. On my first facebook account where I made the fb app, I can login successfully to the website. I logged it out and I can still access the facebook app but when I'm trying to login a different facebook account, it gives me this error:

Anyone can help me solve this issue?
