Anybody know what is this error mean?
"Call to a member function on a non-object in includes/db_function.inc".

It seems that it cannot access one of the function of my Database connection object but I have already passed the connection object by reference to the function which call the db function.

Can you show us a little more code there must be a problem with the way you ar trying to call the function.

you're calling a method from an instance that does not exists.. in other words.. if you're using the function (method) of the instance in another function, use "global $[instance name]" to declare it.

Thanks. I have found out the problem is in the argument order I have passed to the function
