Invalid auth state parameter

Hello,

I have problems with Facebook login / registration in Yii2 using Yii2-user and Yii2-auth.

When I click on "Login with facebook", I get this error:

404 error, Invalid auth state parameter

I think it has something to do with Facebook API version. When I try to connect FB app created in v2.7, I don’t get the message. I created a new FB login in v2.9, but I got this error.

Can anyone suggest? I try to update all extensions etc. to the latest state, but was not successful.

Thanks!

Ok, the problem was that some YII2 folders were missing on the server (session, tmp)

Hello! I have same problem. Can you tell me what did you do? Where I must create folders?

Thanks
