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.
This is one of the reasons I quite scaring my wife. Poor Merv.
Your wife is like me… Scare me and I’ll kill you! LOL
