After I put up my last post, I noticed that partway down, a vertical black line has appeared on the left side. The line continues along the side of the last few posts and then stops. It comes right up to the margin for text and photos but doesn't quite obstruct anything---just distracts. The last few posts have had a lot of photos, if that might have anything to do with it. It is still there when I log out and log back on. Any ideas?
The blog I need help with is streamsandforests.wordpress.com.
