 * I was because of an incomplete function in theme file function.php
 * what actually happened? I added a function and later removed that but not complete.
   the following part was left unremoved
 * `add_action('admin_footer', 'dpbc');`
 * so I you also watching the similar errors on your admin footer. try finding incomplete
   function.

 * Turn off all the plugins and use one of the bundled themes. If that error still
   shows up then there is something wrong with the WordPress install.
 * Once the notice goes away, turn on the theme you are using and see if it comes
   back. Repeat for the plugins.
 * That means that when plugin.php is using the call_user_func_array() it expects
   to be able to call another function (that is what the PHP function does). It 
   can’t find that other function so you get an error.
 * It could be that you have a partial plugin download even. So it’s looking for
   a function and it’s in a file you’re missing. Same could go for the theme, or
   really for the WordPress install, but I would put my money on the theme or plugins.
