The problem I had was that I upgraded to 4.2.3 and the php code conventions had changed. Has to do with how the sessions are handled. I could login so I made a database call but after that it would not work correctly. The ODBC connection which uses a fetch statement needed to be changed. Here is what I put in and it works fine now.
//$stat = odbc_fetch_into($this->Query_ID, ++$this->Row,
// $this->Record);
$stat = odbc_fetch_row($this->Query_ID, ++$this->Row);
I hope this works for you.
