How is it misquoted?

A few years ago, I read that the correct phrase is, "Those who do not learn from the mistakes of history are doomed to repeat them."

This version makes more sense than the commonly quoted phrase, which implies that nothing from the past is worth repeating. That is patently false and indefensible and is why I would never use the common phrase to make a point.

Question: was Santayana misquoted? Or merely wrong?

Your version is the only one I've ever heard. What is the misquoted phrase, just out of curiosity?
