 * Hi I’ve recently installed 2.3.3 but it gives me this error messages on the main
   page:
 *     ```
       Warning: call_user_func_array() [function.call-user-func-array]: First argumented is expected to be a valid callback, 'sanitize_comment_cookies' was given in /home/toffee/public_html/wp-includes/plugin.php on line 164
       ```
   
 * and on the log-in page:
 *     ```
       Warning: call_user_func_array() [function.call-user-func-array]: First argumented is expected to be a valid callback, 'sanitize_comment_cookies' was given in /home/toffee/public_html/wp-includes/plugin.php on line 164
   
       Warning: Cannot modify header information - headers already sent by (output started at /home/toffee/public_html/wp-includes/plugin.php:164) in /home/toffee/public_html/wp-login.php on line 12

       ```
   
 * plus, it doesn’t let me log-in. It says: **ERROR: WordPress requires Cookies 
   but your browser does not support them or they are blocked.**
 * what should I do?
