Fatal error: Call to undefined function mysql_die

After i transfered my site into a new host this is what i get when i open the main pages :

"Fatal error: Call to undefined function mysql_die() in /home/mysite/public_html/index.php on line 27 "

line 27 of index.php is this : $result = mysql_query($sql) or mysql_die($sql);


any idea how to solve this problem? :confused:

thanks!

It seems the problem with config.php.

Have you changed the config.php file with new host database details ?
