I'm updating from 3.0.1 to 3.0.4. After completing the backups and the WP upgrade, the stage at which the plugins get reactivated is broken.
wp-admin/index.php brings up:
Fatal error: Call to undefined function get_option() in /hsphere/local/home/.../wp-admin/admin.php on line 22
wp-admin/plugins.php brings up:
Parse error: syntax error, unexpected $end in /hsphere/local/home/.../wp-admin/plugins.php on line 210
I have restored from the backups and upgraded using WP's built-in update module.
