I think I had the same or similar issue. My blog page was always showing on the main page, so I could only add widgets to the Blog-Sidebar. I messed around with the settings for a while and figured the problem should be stemming from the “bphome” theme. My solution; given that I hadn’t made any modifications in the back, was to just download the latest bphome theme and do a little switcheroo. Delete the faulty put the new in. Hope that helps.
