CI cannot load models

Hello WanWizard:
Thank your for your reply and for the explanation.
However things are not working on the error reporting front.
I have the following directive in both /etc/php5/cli/php.ini and /etc/php5/apache2/php.ini:

Code:

; display_errors = Off
display_errors = 1

I still have a blank screen. Please note the following code snippets from index.php:

Code:

echo "hello 1 (precedes the call to error_reporting)<br>";
error_reporting(E_ALL);
/* Remainder of code for index.php follows */
.....
/* more debugging: last lines of index.php */
echo "hello 2 (precedes the call to require_once)<br>";
echo BASEPATH.'codeigniter/CodeIgniter'.EXT.'<br>';
require_once BASEPATH.'codeigniter/CodeIgniter'.EXT;
echo "hello 3 (follows the call to require_once)<br>";
/* End of file index.php */
/* Location: ./index.php */

Now here is the output:

hello 1 (precedes the call to error_reporting)
hello 2 (precedes the call to require_once)
/home/http/php/ci/system/codeigniter/CodeIgniter.php

I infer from the output that CI is aborting at the call to require_once
Note that there is no error reporting.
