Clear your browser session and browser cache.
Took quite a while, but this did it, I could log in.
However, after that, posting a comment to the blog did not work...clicked 'Preview,' then 'Post,' nothing happened, no obvious posting of the comment.
Also, after logging in, then closing the browser tab/window, the website login appears not to persist -- is this how it is supposed to work?? The forum login persists but website logins do not persist??
Thank you, Tom
