Get my website online

I have websites that are already designed but there has been an error which can be viewed at www.chaletborovets.com. I need the error fixed so I can get all my websites back online. The files for the websites are already there as it is my own server as well. This should take minimal time and effort for which I am offering payment. I'd be happy for anyone interested to take a look. There would also be other jobs in line for the suitable person.
