# Admin section doesn't work after server change

 * I recently upgraded my service from 1and1.com business to the performance package.
   1and1 takes care of the migration for you. Several of my WordPress websites were
   moved (running version 3.3). The frontend of the site works fine (example: [http://www.unexpected.org](http://www.unexpected.org)),
   but the admin section doesn’t work. I’ve uploaded a screencapture at the link
   below:
 * [http://www.cisternmedia.com/projects/unexpectedscreenshot.png](http://www.cisternmedia.com/projects/unexpectedscreenshot.png)
 * As you can see the left side nav shows up fine but the right side content does
   not. It worked fine on the previous server. Both servers run php 5/mysql 5. Any
   ideas what might be causing this issue? I’ve submitted this question to 1and1
   as well, but I’d like to resolve this quicker.

 * Hey Alex,
 * I do work for 1&1 but It’s a shame I don’t have that kind of access to help you
   out better yet. What I could imagine what would have happened is that your PHP
   got upgraded during the move. You could give me more information to enable WP_DEBUG
   in your wp-config.php file what is in the main folder of WordPress. You will 
   see that the value is false, if you can make that to true you will see more information.
   And that information helps me to identify your issue.
 * Best,
    Marko

 * Figured out issue. There is a bug in WordPress 3.3.1 that causes the issue. To
   fix:
 * 1) Opened file ../wp-admin/includes/screen.php
    2) On line 706 found the following
   PHP statement: <?php echo self::$this->_help_sidebar; ?> 3) Replaced it with 
   the statement: <?php echo $this->_help_sidebar; ?>

    Glad you got it working but
   modifying core files is never recommended unless you plan on never updating WP
   again. During the next update, any changes made to the core files will be wiped
   out.
 * Another note: 3.3.1 is way outdated… Updating would always fix your issue :)..

    In general you are right
   but in this case It’s kind of patching WordPress due the fact that WordPress 
   did something similar. That said Alex really should update his installation.

 * I know. I just needed a quick fix. The more current versions of wordpress fix
   the issue, so it’s okay if my fix is overwritten.
