I just installed Atahualpa 3.6.7 here - http://elizabethedwards.me/
The first thing I did is go to Style & Configure Sidebars and uncheck all the boxes for the left sidebar. I clicked the big Save button, refreshed my site, and the left sidebar was still there. I tried again, and again. What am I doing wrong?
SOLVED: still no idea what happened, I reset the options and unchecked the boxes again, and this time the left sidebar went away.
