I am running several wordpress installs under one domain name. I have just upgraded one of them to 2.2.3, but when I visit upgrade.php, I get a message saying that the data base is up-to -date. Then when I try to open the site, I am taken to the dashboard panel of the main domain name. All the files are in the directory, all the admin functions are there, but when I click view site, I get taken to the dashboard again. I am not very code-savvy, but have a basic understanding.
