Problems updating to latest wordpress version

Hi everyone,

I recenlty updated to the latest wordpress version from 4.1.8, but after I did that, I wwas kicked out from my dashboard and couldn’t log back in. As of right now, everything is dead, front page and back office. Here are the links:

Web page
WP admin

What’s weird is that not even an error msg appears on the screen, no explanation of any sort.

Any help or recommendations?

Thanks.
