The custom LoginHandle cannot be instantiated, and the mysql test can be linked... I don't know why...
LoginHanlde. php

 Ini_set ("error_reporting", "E_ALL &~ E_NOTICE ");
Include '../bld_controller/LoginHandle. class. php ';
$ Username = $ _ POST ['username'];
$ Password = $ _ POST ['password'];
$ Login = new LoginHandle (); // stops running this step.
$ Flag = $ login-> check_psw ($ username, $ password );
If ($ flag)
{
Session_start ();
$ _ SESSION ['username'] = $ username;
Echo"
