    Hello There,

    I got the following message while trying to upgrade wp 3.3 automatically.

    Fatal error: Cannot redeclare class Plugin_Upgrader in /home/advert/public_html/wp-admin/includes/class-wp-upgrader.php on line 594

    Any solution to the problem?

    Thanks in advance.

    Best Regards,

    Have you gone through this checklist?

    I'd disable all plugins before doing the upgrade. If that doesn't work try doing a manual update.
