First don't mark it as duplicate because this is new issue came, there was no issue before for this, on server in error file it give this to me "CSRF state token does not match one provided." AND I TRIED ALL SOLUTIONS FROM THIS PLATFORM and also did replaced getCode function in base_facebook.php file as was mentioned in one of the solution.
And with that solution that started working perfectly but from yesterday it is again giving same error and not working, when I click on continue with facebook it keeps generating new auth call with new code.
Please help with that, here is the live test link to it: http://eliteware.co/92/login/
Click on continue with facebook and you will get it.
As I am troubleshooting the code, this line $facebook->getUser() always returns zero in php code.
