There are currently no widgets assigned to the left-sidebar, place some!
Once you add widgets to this sidebar, this default information will go away.
Widgets can be added by going to your dashboard (wp-admin) -> Appearance -> Widgets, drag a widget you want to see into one of the appropriate sidebars.
I don’t know about the back of your neck, but when it stands up on your partners head like that it means “RUN!!”
You’re pretty smart!
LOL
