Fatal Error! Please Help!

  • Hi guys —

    I tried to log into a site a built and I can get to the wp-loing.php page but when i put in my username and password i get this error! It doesn’t let me go any further, just from login in page to error page.

    Fatal error: Call to undefined function wp_is_mobile() in /home/content/62/9061362/html/wp-admin/admin-header.php on line 90

    I tried to reupload the admin-header.php with no success. It’s odd my site is still working perfectly at the URL, I just can’t log into wp admin and change anything. I really don’t want to have to rebuild the whole thing :S

    Thank you for any help!
