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?
