i burned a few cycles on this issue, and just resolved it, so i thought i'd share.
i verified that:
but wp was not automatically going to the https://me.com/wp-login.php for logins.

after some head scratching, on a lark, i moved the line:
from the bottom of wp-config.php to the top and lo-and-behold it started working.
so beware, the line placement order !!! ;)
