This is my first time using WordPress. My client hired someone to create a site for him with a custom template in wordpress and he is hiring me to finish the site. I tried to update wordpress yesterday to the latest version and clicked to update all plugins, and I'm not sure the update was successful. Since then, when I go to the log in screen I see this at the top:
Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'sanitize_comment_cookies' not found or invalid function name in /home/content/92/10622692/html/tmp/wp-includes/plugin.php on line 406
Fatal error: Call to undefined function wp_count_comments() in /home/content/92/10622692/html/tmp/wp-admin/menu.php on line 94
When I go to the homepage online I see: the same error throughout the homepage.

I am concerned that I can't even get into the code to fix anything...
