WordPress seems to be using the correct URL for the upgrade https://www.site.com/wordpress/wp-admin/upgrade.php?step=1&backto=%2Fwordpress%2Fwp-admin%2F
In fact, I should mention, the wp-admin screen looks like it was, indeed, upgraded to 2.5. I get the “Upgrade Complete. Your WordPress database has been successfully upgraded!” message. But when I hit “continue”, it takes me back to the page that says “Database Upgrade Required. Your WordPress database is out-of-date, and must be upgraded before you can continue. The upgrade process may take a while, so please be patient.”, so I’m back where I began.
My WordPress installation has not changed directory structure.
Thanks. ??
