I'm trying to upgrade from version 2.0 something to 2.3.1. I've uploaded everything and followed the extended upgrade instructions carefully but can't get the upgrade.php script to run. Here's the message I get when I type http://www.wmccnews.com/wp-admin/upgrade.php in my Firefox browser:
Warning: main(/home/wmccnews/public_html/wp-settings.php) [function.main]: failed to open stream: No such file or directory in /home/wmccnews/public_html/wp-config.php on line 20
Fatal error: main() [function.require]: Failed opening required '/home/wmccnews/public_html/wp-settings.php' (include_path='.:/usr/php4/lib/php:/usr/local/php4/lib/php') in /home/wmccnews/public_html/wp-config.php on line 20
