He added a code in my site footer.

<!--807e156811a5add9c156bb70d306d523-->

And site error is:

Warning: Cannot modify header information - headers already sent by (output started at /home/.../public_html/it/lang/english/main.php:391) in /home/.../public_html/it/includes/sessions.php on line 101

Warning: Cannot modify header information - headers already sent by (output started at /home/.../public_html/it/lang/english/main.php:391) in /home/footpic/public_html/it/includes/sessions.php on line 101
