edwonI am getting this weird error all of the sudden when attempting to login.
Fatal error: Call to undefined function is_network_admin() in /home/schultzf/public_html/wordpress/wp-admin/admin-header.php on line 16
I have gone through some other troubleshooting steps suggested (including removing all plugins from the plugins folder) and still no luck. I have also searched through the forums and not found this specific error. Please help.
