Dang... Something went wrong

I am experiencing problem with G3 1 version prior to the latest. 3 days ago I uploaded pictures, and the gallery stopped working. I can't get in using proper user name and password, the login screen just keeps coming back without eny error messages. However when I type proper user name and wrong password, it states invald login/password, next I am entering proper credentials and that's when I get the "Dang... Something went wrong"

var/logs have this entry in todays log

It does not make too much sense to me, perhaps someone can give me a hand. I have uploaded fresh download of G3 over existing files, database.php was backedup to preserve configuration. Still no go...
