Received this warning on the User section, under Your Profile area:
Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'proofread_bot_config' was given in /home/XXXXX/public_html/wp-includes/plugin.php on line 406
Note: I removed the folder name where you see XXXXX in the Warning above for security reasons.
Running all the latest WordPress Updates as of today Jan 24, 2013
The Warning goes away if by Disabling the Proofread Bot plugin.
Any ideas as to how this is effecting WordPress and if it can be fixed?
