 * I just updated this morning.. everything seems fine..
 * But when I clicked on the users in admin panel.
 * Fatal error: Call to undefined function cache_users() in /*****/html/wp-includes/
   user.php on line 562
 * I got such fatal error.. what I do now?? please help!
 * ———-
    this is part of the script near line 562.. By the way, I didn’t edit any
   script at all.
 *  if ( ‘all_with_meta’ == $this->query_vars[‘fields’] ) {
    cache_users( $this-
   >results );
 *  $r = array();
    foreach ( $this->results as $userid ) $r[ $userid ] = new WP_User(
   $userid, ”, $this->query_vars[‘blog_id’] );
 *  $this->results = $r;
    } }

 * Have you tried:
 * – deactivating **all** plugins to see if this resolves the problem. If this works,
   re-activate the plugins one by one until you find the problematic plugin(s).
 * – switching to the Twenty Eleven theme to rule out any theme-specific problems.
 * – [resetting the plugins folder](http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F)
   by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause
   problems.

 * Don;t know why, I reinstall the WP 3.2, and now it’s fixed by itself..
 * Thanks anyway, esmi
