 * – then try **MANUAL** updating. Download a fresh copy of the WordPress .zip file
   to your computer, unzip it, and use that to copy up all files and folders EXCEPT
   the wp-config.php file and the /wp-content/ directory. You may need to delete
   the old copies of files & folder on your server before uploading the new ones.
   Read the [Manual Update ](http://codex.wordpress.org/Updating_WordPress#Manual_Update)
   directions first.
    – running the upgrade manually via wp-admin/upgrade.php
