# Issues with /wp-admin/ directory

 * I’m trying to upgrade my version of WordPress. In place of the ‘Proceed’ button
   there is this error message: Fatal error: Call to undefined function wp_unslash()
   in D:\Hosting\2434477\html\thederekperkins\wp-admin\includes\file.php on line
   1103.
 * I’ve also noticed there are various other error messages throughout WordPress
   that all link to the /wp-admin/ directory.
 * I re-uploaded the entire /wp-admin/ directory to see if that would work out any
   kinks, but no luck.
 * Is there anything else I can try to resolve these error messages or would doing
   a complete manual re-install be my best bet?

 * According to the Codex, wp_unslash() is located in wp-includes/formatting.php.
 * So make sure that file is there.

 * In this case, I’d recommend upgrading manually just this once: [https://codex.wordpress.org/Upgrading_WordPress_Extended](https://codex.wordpress.org/Upgrading_WordPress_Extended)
 * That should resolve the issue going forward.
