Logged into the wp/admin and was greeted by a message saying I need to update my database, when I did I now get the message:
Fatal error: Call to undefined function is_main_network() in /homepages/36/d120614115/htdocs/wp-admin/includes/schema.php on line 564
The site clairespooner.com is still online, but I cannot log into the dashboard at all.
Really grateful for any help.
