Error in include when uploading site [closed]

Hello! I'll be brief. I'm having problems on 000webhost.com server. Upload my test site to check how the facebook login would look on the air. The error is this:

  

Warning:   include (/storage/ssd2/781/3154781/public_html/lib/Facebook/autoload.php):   failed to open stream: No such file or directory in   /storage/ssd2/781/3154781/public_html/users/loginFace.php on line 6

     

Warning: include (): Failed opening   '/storage/ssd2/781/3154781/public_html/lib/Facebook/autoload.php' for   inclusion (include_path = '.: / usr / share / pear: / usr / share / php') in   /storage/ssd2/781/3154781/public_html/users/loginFace.php on line 6

     

Fatal error: Uncaught Error: Class 'Facebook \ Facebook' not found in   /storage/ssd2/781/3154781/public_html/users/loginFace.php:10 Stack   trace: # 0 /storage/ssd2/781/3154781/public_html/index.php(2):   include_once () # 1 {main} thrown in   /storage/ssd2/781/3154781/public_html/users/loginFace.php on line 10

Part of the code where the error occurs:

if(!isset($_SESSION)) { 
   session_start(); 
}

include($_SERVER['DOCUMENT_ROOT'].'/lib/Facebook/autoload.php');
/*require('../lib/Facebook/autoload.php');*/

unset($_SESSION['face_access_token']);
$fb  =  new  \Facebook\Facebook([ 
'app_id' => '1511055948960318' ,
 'app_secret' => '710b34a0395d103abdbfe8909878e82e' ,
  'default_graph_version ' => ' v2.9 ' , 
  // ' Default_access_token '=>' {access-token} ', // opcional
]);

The code on the Wamp server works perfectly. All folders and subfolders are correct. can anybody help me? Thanks!
