girlieworks on "Errors since php and mysql upgrade if anyone can please help?"

Hi just did a server upgrade and now apache error log gives me this:

mod_fcgid: stderr: PHP Fatal error: Uncaught Error: Call to undefined function mysql_query() in /home/public_html/wp-content/themes/DynamiX/functions.php:118
od_fcgid: stderr: Stack trace:

Any help to fix would be really appreciated, it's using Dynamix theme. Thanks.
