Failed to find the Facebook client libraries While trying to configure Drupal for Facebook, I followed the readme and copied their code into my settings.php and placed the facebook-php-sdk file into the stated location under sites/all/libraries but I still get this error:


  Failed to find the Facebook client libraries at sites/all/libraries/facebook-php-sdk/src/facebook.php. Read the README.txt and follow the instructions carefully.


I went to publichtml\sites\all\libraries\facebook-php-sdk-master\src and www\sites\all\libraries\facebook-php-sdk-master\src to check if facebook.php exists to be sure and it's there.
It's looking for the file in sites/all/libraries/facebook-php-sdk/src/facebook.php, while your file exists in publichtml/sites/all/libraries/facebook-php-sdk-master/src/facebook.php and www/sites/all/libraries/facebook-php-sdk-master/src/facebook.php. The difference is between facebook-php-sdk and facebook-php-sdk-master.

Change the folder name from facebook-php-sdk-master to facebook-php-sdk.
