Upgraded to 2.3.1, but is not recognized

I just downloaded, installed, and ran the upgrade.php file on my blog (www.trowbridgefamily.net), and the admin page still shows that I’m running 2.3, and it’s still giving me the option to download the upgrade. When I ran the upgrade.php, I was directed to a page that said that I have the latest files – no upgrade is necessary. Am I doing something wrong?
