I ran the script on the off chance it would help but I still have the same problem.
Also, here is the phpinfo in case this helps.

Error in error log:
[Mon Apr 02 14:49:48 2007] [error] [client 67.55.186.22] PHP Warning: Invalid argument supplied for foreach() in /home/httpd/vhosts/z-doc.com/httpdocs/wordpress/wp-includes/capabilities.php on line 31
I installed 2.1 with the instructions provided on the wordpress website. Not through plesk.
I tried upgrading 1.5 and that didn’t work so I just removed everything and reinstalled from scratch. Deleted the database too.
