 * When I finally got in, I had this problem in the media sector of the admin panel:
   Warning: explode() expects parameter 2 to be string, array given in C:\xampp\
   htdocs\wordpress\wp-includes\query.php on line 2390
    Warning: in_array() expects
   parameter 2 to be array, null given in C:\xampp\htdocs\wordpress\wp-includes\
   query.php on line 2399
 * Does anyone know how to change this?

 * Your upgrade may not have completed successfully.
    Try: – switching to the Twenty
   Ten theme by renaming your current theme’s folder in wp-content/themes using 
   [FTP](http://codex.wordpress.org/FTP_Clients) or whatever file management application
   your host provides.
 * – [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.
 * – re-uploading all files & folders – **except** the wp-content folder – from 
   a **fresh** download of WordPress.
 * – re-running the upgrade manually using wp-admin/upgrade.php.

 * I can upload all files & folders again, but I downloaded the newest version of
   WP I think, 3.1.3, the Swedish version from the Swedish wp-page. I got the same
   problem before, when I uploaded 3.1.3 SW on an older version of WP on another
   server some months ago. Could there be a bug in the system and is there anybody
   who knows how to fix it? Thanks anyway, I will try some of your suggestions.

 * Try installing this:

 * It solved the same problem I had ! 🙂
