Login Error

Hi All,

I am seeing this on my wordpress login

Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, ‘wp_no_robots’ was given in /home/content/62/5945362/html/sinuatemedia/wp-includes/plugin.php on line 405

What is that? Is that a database issue?

PJ
