I have just spent a buttock-clenching evening updating the software to the latest version and converting all the old posts to the new format.
Hopefully everything went OK and no old posts were lost, if they were, then I fear they are gone forever

Over the next few days you should see the colours/layout start to change as I get to grips with all the new settings. It should settle down in a few days.
