After moving my blog into a new server, my nice permalinks (/%year%/%monthnum%/%day%/%postname%/) seems to give me a 404 error (http://she-falls-apart.org/2007/05/26/fragile-heart/). However, if I switch to default (?p=123) it seems fine. I'm not too sure what is causing this. Could someone kindly help me? Thank you!
