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 think that’s exactly what they do sometimes!
Judging by the insane EVPs that show up sometimes, I’m not surprised! LOL Now you know where the idea came from!
