Fatal Error After Accepting WordPress Update -- Blog Not Operational (2 posts)

    Hi there --

    A client of mine uses WordPress.org domain mapping for his blog and today we were on a conference call adjusting his settings and were prompted to accept an update to WordPress 3.0. After doing so, the update failed, and when I clicked a prompt to try again, I got a scripting error:

    Fatal error: Call to undefined function is_multisite() in /home/content/c/a/r/carrozzaweb/html/blog/wp-includes/wp-db.php on line 505

    As a result, the blog is no longer live! Why did this happen after accepting an update? This should not happen.

    Can anyone help direct me to where I need to go to remove that error? The Web designer who set up the blog hosting is not reachable today.

    Thank you for your help.

    - switching to the default theme by renaming your current theme's folder using FTP or whatever file management application your host provides.

    - resetting the plugins folder by FTP or phpMyAdmin.

    - re-running the upgrade manually using /wp-admin/upgrade.php.
