mysql_* commands have been removed in PHP7 and have been depreciated (not recommended for use) since PHP 4.3.0 (Released: 27 December 2002). I am guessing that someone edited this from the default twentysixteen/functions.php file since it does not include a mysql_escape_string() command.

mysqli_real_escape_string() provides a drop in replacement under the mysqli module (installed in package php7.0-mysql) that should help you resolve this. I would also recommend looking for any other mysql_ type calls in your theme to ensure they are updated or removed.
