title: OAuth Error: This IP can't make requests for that application
body: <p>I just started to get random <code>This IP can't make requests for that application.</code> errors with my app. My server's IP address is on my whitelist from my app's settings, and it was working perfectly, but I randomly started to get this error. I've checked my server's IP (even though I already know it's static), I've removed all the entries in the whitelist, but none seem to work. Weird enough, I can test the exact same code from my home and it works! What could be the cause of the problem? This wasn't happening even a few minutes ago, but now I'm getting an error at my server.</p>
  
  <p>Thanks,
  Can.</p>
  
  <p><strong>UPDATE</strong>: I can't seem to remove the whitelist, too. I went to app advanced settings, and the IP's were there again. I deleted them and saved, it says that it's saved but when I scroll down, the IP's are still there. I think it's a serious bug with Facebook. But that [currently un-editable] list DOES contain my server's IP anyway.</p>
