so I tried to automatically update to wordpress 3.4.2, but in the middle of the process it stop and said there was some maintenance being done. Now when I try to go to my site I get this :
Fatal error: Call to undefined function wp_is_mobile() in /home/content/62/8984162/html/wp-admin/index.php on line 24
As soon as I log in I get the same message....
Can anyone help me?
