Manal and Alaa's bit bucket

I'm facing a strange problem in my drupal blog (ikhnaton2.com/whisper). It was working fine but suddenly I can't browse it and see this error:

Warning: ini_set(): A session is active. You cannot change the session module's ini settings at this time. in /home/ikhnaton/public_html/whisper/sites/default/settings.php on line 128

I tried to comment (line 128) ini_set('session.save_handler','user') in settings.php as being adviced in (http://drupal.org/node/84904) but it gives me the following error:

and browsing to any page (even home page) gives:

Access denied
You are not authorized to access this page.

I tried to add those lines to .htaccess file but no difference:

php_value "memory_limit" "32M"
php_value session.cookie_domain ".ikhnaton2.com"
php_flag register_globals on
php_value "max_execution_time" 600

Do you have an idea to solve this problem?
