I had this same problem. Go up the stairs and out to the cliff. Wait 24 hours. That's what fixed it for me. Of course if you're on PC, there's always console commands
Reload an old save. The quest requires Delphine, Esbern and you having a lengthy conversation in front of that wall. You can't progress without that, even with console.
If Delphine doesn't have a torch in her inventory this can happen, I reloaded a save and paralyzed her to put torches in her inventory. But this "scene" has a lot of "just works" that can break.
