My host upgraded their servers this afternoon. This included new mySQL server addresses, new DNS nameservers, upgrade to PHP 5.2.17, mysqld 5.0.67, phpMyAdmin 3.4.4, and other software I don't use. They automatically went in to the FTP server, backed up the files and changed the mySQL IP addresses to the new ones. I doublechecked with WinMerge and these were the only changes I could find.

For the first hour or so, I couldn't access the Zencart Admin login page. Then it came alive.

Now, when I enter the correct username/password and press enter, it comes back with the same login page, but the username and password I just typed is gone. Entering an incorrect username and password returns the standard login error message. This behavior is present with both Firefox and Internet Explorer.

So, as of now, I can't access the Admin pages.

I believe I'm running 1.3.7.
