We're aware of a problem with liquidsoap that's occurring when some of you are trying to start your servers. This has been caused by a buggy update Centova have pushed which was applied to some of our servers. We've informed Centova and hope to have a solid fix applied ASAP.
In the meantime, we know how important getting back up and running is to you all - this will help:
Login to Centova Cast, go to Settings -> Mount Points, then select '/stream' or any other appropriate mount points, go to AutoDJ settings and change the sample rate from 44100Hz to 48000Hz, press update and start your server.
