Facebook OAuth working, but getting errors on /logs page


I just set up login with Facebook on my Discourse site, and from my testing everything seems to be working. However, I keep getting this error on my /logs page:

(facebook) Authentication failure! no_authorization_code: OmniAuth::Strategies::Facebook::NoAuthorizationCodeError, must pass either a `code` (via URL or by an `fbsr_XXX` signed request cookie)

Does anyone have any thoughts as to what is causing this?

I am updated on the latest version of Discourse.
