    Whats up with that?

    I upgraded from 2.9.2 to 3.0 using the automated option from inside my WordPress admin section.

    As soon as it finished unpacking files, I got a blank screen.

    When I review my log files, all I see is:

    [Thu Jun 17 15:35:11 2010] [error] [client zz] PHP Fatal error:  Call to undefined function is_multisite() in /var/www/vhosts/mydomain/httpdocs/wp-includes/wp-db.php on line 505

    wtf?? It did not even prompt me for a database upgrade or anything.

    I then went and manually downloaded the wordpress 3.0 files and uploaded them myself overwriting the old files.. I still get blank pages everywhere.

    Cannot get to wp-admin.. cannot run wp-admin/upgrade.php or anything.

    What am I supposed to do now?

    ok .. I'm back up and running. I simply downloaded 3.0, unzipped and uploaded/overwrote JUST the files in the root dir, nothing else. Phew!

    Thank you. I fixed it already.

    all you really need to overwrite is wp-settings.php

    I have no knowledge of PHP I am a newbie to all this programing of a thing, moreover ‘am unable to sign in into my FILEZILLA Ftp. Everything is not working for me please help.

    Every advices is welcome.

    I received the same error on my automatic upgrade. I am presently working through everyone’s solutions to see what will correct the issue

    (Simply replacing settings.php prompted an additional error.)

    I will post again if I am able to fix, or to let you know if my problem remains unresolved.

    I got the same error as the thread starter. Exactly the same situation.

    “all you really need to overwrite is wp-settings.php”

    I will try this.

    yes, overwriting wp-settings.php also worked for me, way easier than a full backup and restore.
