I have the same problem. I walk up to ladders, I can't climb them, I try jumping at them whilst holding forward, nothing happens. Help us!
-Edit-- I have found that without my mods and only Optifine, it works, the problem may be Forge.
-Edit-- It was indeed Forge that was messing it up. take it out and use modloader instead.

I have the same problem, but when I first installed forge it was fine. After about 2(real)days I couldn't climb ladders.

It's Minecraft itself. Restarting the game should resolve the issue.
