While attempting to upgrade from 1.4 to 2, I sort of got everything working. Unfortunately, I was unable to login. Thinking I might have typed the password in wrong when setting it, I attempted to reinstall by dropping the ojs2 database from mysql and deleting the ojs2 directory from htdocs. I then untarred ojs into that directory, changed the permissions as the README specifies, and re-created the ojs2 database. Now, when I go to the directory via a web browser to run the install script, it outputs:
Fatal error: Cannot redeclare class virtualarrayiterator in /var/www/localhost/htdocs/ojs-2.0/includes/functions.inc.php on line 21
Is there some more installation information from the previous install hiding somewhere that I didn't purge yet?
