Commenting out line 111 works for my account (facebook developer account only). But other people get empty page.
I'm using Flarum with Nginx 1.10 at Vultr.
Here is the error log:
2017/04/15 08:28:31 [error] 28997#28997: *179 FastCGI sent in stderr: "PHP message: PHP Deprecated: The third argument to Zend\Stratigility\MiddlewarePipe() ($out) will be required starting with Stratigility version 2; please see https://docs.zendframework.com/zend-stratigility/migration/to-v2/ for more details on how to update your application to remove this message. in /var/www/flarum/vendor/zendframework/zend-stratigility/src/MiddlewarePipe.php on line 101" while reading response header from upstream, client: 42.116.152.202, server: eggpresso.space, request: "GET /auth/facebook?code=AQBJmiNMZAn3b0_gJ--0GtIHg6ZsBmQ55BdLQgj3l6Xgx_yZMCMQ0FFcarQIgaYKWr9uoM5-V4Ltw4xQ4rA5Q9_sfZVgRoaBVnFjTGzD673THxrvcI58lkTib50txKesWeQu3MzZ5zICRGalAPfGyn3_EEV-hfqJe-W6OMbXbOJGRCvPpuDoD6Q4FZ_k0Q05UvfWgTm2e8auuEB82AdWDd8O3s_DnVeG4qZbr-mA3FRQsp3_1VytNbdWgFn6sWwjFL5XgyMl_WI-XYfV8FUUlW7WxgFC-R2CV7Oev7kUJYS9o_d-uTcYIuCO2ehmUuFyoAW3GTH-JAHD4jhyM8oDLEpnUwnas9HsC4ckRvRULB49CA&state=Wxw3TP9BbEwgsnnriMrtLV8We7NsYdhW HTTP/1.1", upstream: "fastcgi://unix:/run/php/php7.0-fpm.sock:", host: "www.eggpresso.space", referrer: "http://www.eggpresso.space/"
