# Help with reinstallation after trying to update

 * Greetings,
 * Aftering updating my blog to WordPress 4.4, I have encountered an error that 
   I am at a loss to fix. When I attempt to log into my Dashboard, I get the following
   error message: “Fatal error: Call to undefined function wp_removable_query_args()
   in /homepages/14/d92438909/htdocs/wp-admin/includes/misc.php on line 900” I have
   tried some troubleshooting, including disabling plugins via FTP and resetting
   to the default theme – nothing seems to work.
 * So, it seems I need to now reinstall WordPress. Fortunately, I did backup my 
   database (using the backup function in my Dashboard) before attempting to upgrade
   to 4.4
 * My main question is, how do I reinstall WordPress with this existing backup. 
   Do I just do a clean install and then import? Or something else? I’m not completely
   proficient when it comes to this type of installation, so any help would be greatly
   appreciated. Thank you!

 * No, just reinstall the core files, nothing else.
 * Try [downloading WordPress](https://wordpress.org/download/) again and delete
   then replace your copies of everything **except** the `wp-config.php` file and
   the `/wp-content/` directory with fresh copies from the download. This will effectively
   replace all of your core files without damaging your content and settings. Some
   uploaders tend to be unreliable when overwriting files, so don’t forget to delete
   the original files before replacing them.

 * Thank you for the response!
 * I followed your instructions and am partially up and running. I’m able to login
   to my dashboard and my content appears to be intact. However, whenever I try 
   to load a post on my blog, I get an error that the page does not exist. Do you
   know how I might go about fixing this issue?
 * Thanks again for your help!

 * Try re-saving your permalink structure at Settings/Permalinks in your admin panel.
   If WordPress cannot automatically edit the `.htaccess` file, it will provide 
   manual instructions after saving.
