Permalinks and Caldendar/Archived Posts

Hi, I have added permalinks to my blog which seems to work (although a trackback ping to another site didn’t work today). The main problem however is that the caldendar and monthly archives don’t work?

This returns a 404

As do the links from the calendar – these don’t have the right address in any case…

I think it is all to do with the permalinks. My mod_rewrite rules are below…

Any help and comments gratefully received! Thanks 🙂
