I seem to have the same problem:
I have a menu (Category type) set up to show only posts of a specific category.
Previously, the distance between each post and the one below was always the same. Now, it seems that each row has a specific height, so if a post is “small” there is a huge blank between that post and the one below. Thankfully, I only updated locally, but I would like to resolve this so I can update the live version.
For now, I have wordpress 3.8.3 and pinboard 1.1.8. I have a child theme, but the problem exists in both the child and the original pinboard theme. The problem appeared after I updated pinboard and a couple of plugins (which shouldn’t have affected the theme I think). No link, since the live version is currently using pinboard 1.0.7 which works as I want.
Are there some settings I should change to get this to work?
Thanks.
