Hello Tracey. I have managed to resolve this same situation on my website. To complete the update you need to go into the themes page on your dashboard and click on where it says to update the Pinboard theme. When you do that the matter should resolve itself.
Good luck
I have found the same problem. I just uploaded the most recent WordPress update and now my homepage is in dissaray. The blog posts no longer appear, and the formatting is messed up. What can be done to correct this?
