    PHP Fatal error: Call to undefined function is_network_admin() in /home/kriswb/public_html/wp-admin/admin-header.php on line 16

    I am getting this error on my site, im running 3.0.5.

    All of a sudden today when i log into wp-admin i get taken to a 500 internal server error page.

    I haven't changed any plugins, none have been updated, no new themes or alterations. Just new content as in posts and media.

    Can anyone help me solve this?

    Your upgrade failed. Try upgrading manually.

    This is ridiculous. Why can't the WordPress team fix this issue which has been happening for the past several versions?? Why even have an auto-update if it never works?

    Agree with pixelrage completely... the fact this is still an issue is crazy.

    A lot of issues regarding the auto update are to do with your hosts server settings ...
    I had no end of trouble until they updated their settings and now all my sites auto update without issue. I'll give them an email to see what they did and i'll report back when i get a response ... BBS

    I have an Atahualpa theme that I have tweaked just how I want it... on the 5th of this month I clicked Update WP on the dash and now I can't log in to the admin at all. I don't want to lose everything I have done on the site previously. Any ideas? I am hosted with godaddy.
    TIA

    Updating manually as mentioned above by Otto did the job for me :). Thanks!
