Conflict with WP theme

Yes, I read that article. I was able to fix the problem above by updating the theme but I’m still struggling with other conflicts.

This is the code in the header.php file:
// Includes the jQuery framework
if( !is_admin()){
wp_deregister_script(‘jquery’);
wp_register_script(‘jquery’, ($themePath .”js/jquery-1.7.min.js”), false, ‘1.7’);
wp_enqueue_script(‘jquery’);
}

// calls hook to WordPress head functions
wp_head();
?>

This is the code in the footer.php file:
<?php wp_footer(); ?>

Is this a problem because the jquery is hard coded to jquery-1.7min.js? I don’t know how to fix this.
