问题
A few days ago I manually installed facebook SDK 5.0 and the login module so users can login with facebook. It worked great until yesterday. When I try login the page loads for 1 minute and then an empty page apears with the error:
Facebook SDK returned an error: Stream returned an empty response
the url looks like this: http://example.com/calls/login/loginFb.php?code=AQCCasdfSAD35L-3iABFbT5zntYQ4jJHVcko9ekG-6k-jn5aERodXoasdf7jHWEgSxxqze_K-nyAYSmcASDFaskde6wPasdfD8WHBEFUEO5gNpgLU0RJqnvVGCdYKNfT2Qm5U1pcWCvVE_YkJ6sQyUL0RrcONrqMbb7bpPv0KDUQjaO_XMAwvKEo2Jasdf31PCjxoHBGoogupX8VF5Gx6WaT4b7ZlsYkPhbQPTCdJaWrzwvfJ1So27Wsdt1Ub9WPUO07io3vxmX-P-rmzsxnk3qDSKCPJX9ks0eBtNwXA-83&state=74096150eesdfbe5eb16bffaa58#=
There is not much useful information about this error on the internet, so I tried the following things:
- Install facebook SDK5 with composer
- Copy the login example from the facebook developers site which is different than the code I used before, but the same error
- Generate new app ID and app secret
Non of the above worked. I run php 7.0 on a debian 8 server.
