I'm not sure why, but I'm having some trouble with the static front page on my blog. It's been up for about a week, and I didn't have any issues with it until yesterday. I would tag selected posts as 'sticky' and they would appear in the showcase block at the top of the page. Yesterday, for whatever reason, I opened my blog to find that the page I use as the front page had disappeared. I made a new version of this page, and everything looks exactly the same, but for whatever reason, only the old sticky posts are displayed on the showcase and new sticky posts are not. I haven't reached the maximum number of showcase posts, as I only have 5 at the moment.
The blog I need help with is mostlyharmlessscience.wordpress.com.
