I’m embarrassed to say that I tried (and somewhat) succeeded adding that bit of code you mentioned yesterday, but now cannot figure out where I pasted it and can’t seem to undo it. It is only applying when I’m using the Moesia theme, so I must have somehow edited the code of that theme but can’t find what exactly I edited. I actually deleted the Moesia folder from my computer and re-downloaded/installed/activated the theme on WP but it’s still messed up. Yikes! Any clues of what I did??
As Groggo mentioned, that code doesn’t help because the sidebar is still there, so it now just covers it up.
