Getting syntax error, unexpected 'App' (T_STRING)

Just created new laravel (5.4) project , uploaded into shared hosting

showing following error

 (1/1) FatalErrorException

syntax error, unexpected 'App' (T_STRING)
in HomeController.php (line 1)

what is the reason behind this , why it is showing error in word App , i thinks its default namespace name right? , working fine in local (WIN 10 , XAMPP )

Please help!
