issues after migration WordPress

hi,
I used the Duplicator plugin to migrate a local wordpress installation to the server.
after the end of the migration I receive this error:
bad script owner /home/0/1/dro.123.fr/www.alan-pizza-vaureal/index.php

I gave the rights to web directory 777, but it’s still the same problem.

but the access to the repository wp-content works well ex:
http://www.alan-pizza-vaureal.dro.123.fr/wp-content/uploads/2018/02/main-pizza.jpg.
help please
