Caching an old revision?!

I’m not getting an errors, but despite the fact that the post has been changed, it is still showing an old revision.

I’ve tried:
– Deleting the browser cache
– Deleting the cache in Wp Super Cache
– Deleting and reinstalling the plugin
– Manually deleting the cached files

No matter what, it is not using the current version of the post, and I’m not getting any errors. It recreated the cache, using old data.

I’m not sure where to look to fix it, as it seems to be doing what it’s supposed to, just conflicting with some thing else?
