Failed to find the Facebook client libraries
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.
