Wordpress Fatal error when updating

asked Oct 16, 2012 in Website Builder by SunFun (3,000 points)
hi all
I tried updating WP to version 3.3.2 using the Automatic Update button. It started updating until the almost the end of the process and an error message “500 Internet Server error” displayed. I searched until I found a solution for this which was recovering the permissions and inserting these lines in my wp-config.php file:
I was now able to login to my site again and tried reinstalling the update again by clicking on Automatic update again. This time I got a different error message
 ‘Fatal error: Cannot redeclare class Plugin_Upgrader in /web/XXX/home/wp-admin/includes/class-wp-upgrader.php
I tried disabling all plugins but that didn’t work. Can anyone please help me fix this?
Thanks in advanced

Try downloading  http://wordpress.org/latest.zip , then manuallu using FTP replace the wp-admin, wp-* except wp-contents and .php files inside the WP root dir.
