After upgrading to 2.0.2 I get the following error trying to access the site, or wp-admin/upgrade.php:
Fatal error: Call to undefined function: update_user_cache() in /public_html/wp-settings.php on line 72
One more note, upgraded from 1.5ish version
Any suggestions besides pulling in the backups of settings and config that I made? (been there, done that..)
