Messed up layout in 2010 Weaver

I’m happy with 2010 Weaver but somehow my right sidebar disappeared (setup is one column, right sidebar). I don’t know what I did, but I have checked code and can’t see why it’s not there, all dimensions seem OK. Went over all the changes I’ve made, etc. I’m stuck. I even tried deactivating theme and then loading it again but it remembers all my settings so it stayed disappeared. Would someone be kind enough to take a look? https://www.tonimcconnel.com
