I’m glad that link made into this thread but between the two installs nothing about the mySQL databases changed. I’m going to dig around a little bit in my logs as well as the db tables to see if I can figure anything else out (despite being glad to be functional using an up-to-date copy of wp-login) that might cause things to go funky.

I had this precise problem and doing the re-upgrade as described above solved it. I was also using an old version of wp-login.php from a local install as a temporary solution. Any devs know what the reason for this sudden failure might be? I’m just curious as a preventive measure in the future. Thanks to everyone for all of the suggestions and solutions.
