Before 2 days there was a automatic update for wordpress, which I for my website.

When the update was over, I tried to access backend but I always get this message:

Fatal error: Call to undefined function wp_is_mobile() in /home/*******/public_html/wp-login.php on line 67 

Can you give me any idea what to do, how to fix this. Thanks
