This is driving me crazy >=(

$facebook->getUser() works well sometimes, but sometimes returns 0

Here is my code: require \'fbapi/facebook.php\';
$

Answer 1

I found a simple solution to this problem.. this happens when facebook class is not able to set or add session variable on your server..

In my code i used session_write_close() before including facebook classes because of which i got this error.. "CSRF state token does not match one provided."..

I then moved session_write_close() at the end of the code and finally it worked.. :)
