The site has been hacked tonight which will result in some very strange messages. The host company (UKHost4U - I can thoroughly recommend them if anyone is looking for a reasonably priced webspace) are currently restoring a backup to a new server, but this might take a while... Just to let you know that it is being dealt with 
I will update here when it's all sorted, but - like I said - it is likely to be a while.
