Titles stopped ‘appearing’ in my published blog posts. Titles are still there when I open posts for editing. Everything was working OK till 2 October 2012. Cleared the cache, tried different browsers – the same issue. No titles.

That’s because you published some of them as Image format posts. If you go to Posts > All Posts, you’ll see “Image” next to their titles. Tick the little squares to select them, select Edit from the Bulk Actions pulldown, click Apply, select Standard from the Format pulldown, click Update.
