Hi there...I have tried to upgrade a blog to the current iteration of WordPress, and now that I have, it seems I have lost everything. I have not deleted the database tables, as it suggests I need to do, because I don't want to lose everything I've been writing for the past two years.
When I run the upgrade.php, the program says that my database is upgraded. Then it dumps me to a 404 page. Something's not right, and I need some help.
