Everytime I try to automatically upgrade it fails for the following reason
Could not copy: html/wp-includes/Text/Diff.php.
When I upgraded from 2.7 something to 2.8 same thing. Now from 2.8 to 2.8.1 same issue. I have to manual delete the wp include file and upload that file again via an ftp site. The text/diff file has permissions so I have no idea why this is happening.
