Gee, the time between posts has been so long that it appears the dashboard has changed. Log in errors show up even after a successful log in. That makes no sense, but so be it. Log in successfully, attempt another interaction, be told not successfully logged in. So I hit the "create a new entry" icon, and we will see what happens. Surely this sort of incident is not happening to just me.
And people wonder why WordPress is so successful?
Simplicity!
