I've been using the WordPress gallery with no problem, but for some reason today I have tried to do it and I am getting the images on a line each, rather than in three columns. And before someone says that there isn't enough room, the thumbnails are quite small and I tried it with only two columns, but it still didn't work. Anyone else experiencing this issue? It is on my blog page here and you can see that I've managed to do it before.
What am I missing?
