I moved by WordPress site to a new host using WordPress move - it worked fine with 2 other sites, but this one didn't work perfectly.
The site is http://www.switch2dvd.co.uk.
After migrating the site to the new server and logging into the admin, it asked me to update my database. I clicked "Update WordPress Database" and it supposedly updated.
The login page is fine, then after that, I get this error:
Fatal error: Call to undefined method WP_Screen::in_admin() in /home/lakerhol/public_html/switch2dvd.co.uk/wp-includes/load.php on line 606
Any ideas? Thanks!
