A couple of things are happening:
After I upgraded to WP 3.1...
-- I can't login to the dashboard. Found a thread on wordpress.org that advised renaming it. I did so, temporarily -- to "functions.old" -- and was able to login.
-- Obviously, with a renamed functions file you can't edit the widgets. So, reverting back to the correct name "functions.php", then attempting to access the Widgets returned an error: "The theme is not widget aware"
Before I go through all of this http://wordpress.org/support/topic/cant-log-in-to-dashboard-3 (I did remove the hardcoded Facebook Like Button - -no effect though) , are you familiar with theme-specific issues that will get me back on track.
Curiously...I don't see "functions.php" in the sidebar of Appearance > Editor...but there is a so called "theme-functions.php" file there.
