Dashboard Error after Upgrade to 2.3.2

I just upgraded my blog Table for Five to 2.3.2. I followed the “Upgrading WordPress Extended Instructions” step by step, including deactivating all plugins. I can see the front page, but when I try to go to table4five.net/wp-admin, I see this:

Index of /wp-admin

* Parent Directory
* admin-ajax.php
* admin-footer.php
* admin-functions.php
* admin-header.php
* admin.php
* bookmarklet.php
* categories.php
* comment.php
* css/
* custom-header.php
* edit-category-form.php

Also, when I tried to run https://table4five.net/wp-admin/upgrade.php, I get “ERROR FOUR OH FOUR-Sorry! That file could not be found.”

What did I do wrong? I checked my cPanel again, and I’ve got WP-Admin, Includes, Content, .htaccess, all the 2.3.2 files-what did I miss?

If someone has a solution please let me know!
