It's possible another add-on you've installed is causing the issue.. suggest using the developer tools in Zen Cart to find out where else that class is being declared..

<?php
/**

*/

function zen_db_insert_id() {
return mysql_insert_id();
}
//EOF

This same function does not appear in any of the other files in the htdocs/includes/functions directory so I am still at a bit of a loss as to what is causing this problem.

Is there any further help you can give me please?

Many thanks
