I've just logged into our wordpress admin panel in order to make some updates to our website. I think we were running version 3.2.1 and were prompted to run updates and install version 3.5. I did this and am now no longer able to enter the wordpress control panel/admoin page. When I try to log in i get the following message:
Fatal error: Call to undefined function wp_get_update_data() in /websites/123reg/LinuxPackage22/ec/ov/ig/ecovigour.com/public_html/wp-admin/menu.php on line 34
Can anybody help? I have a very basic understanding of wordpress and computers so explanations in the simplest terms will be very much appreciated.
