I've just updated my wordpress to 3.5 and can no longer add the featured image to my pages. They still work in posts but not in the pages, where I've used them previously.
I haven't changed my theme, so it should still allow them and when I am in the page editor, I still have the "set featured image" link and can successfully upload an image to there (i.e. I can see the thumbnail on the editing page) but when I preview or update my page, no image shows.
Please could you help me work out what to do to fix this. If anyone has any coding to cover it I'll need a pointer on where to paste it in as I haven't used html coding with my website before. Thanks!
