WordPress Caching Problems

For some reason, this site is caching pages and I’m not seeing updates when the happen – I’m not sure if I’ve done something wrong on my installation (as it happens both at work and at home, I’m sure it’s not a browser problem) – I can’t find any caching options – but the server is definitely doing some caching.

If you post a comment and it doesn’t appear, it’s probably a symptom of this problem!
