Oops! My whole site has gone!

Hi,

I appear to have mislaid my entire site. I get this message:Oops! This link appears to be broken. I have other sites on the same server and they are working so unfortunately it's not a server issue.

So I accidentally deleted my mu-plugins folder, and I was just reinstalling, supporter, upgrades and multi-domains, then I noticed the site was gone.

I have access to cpanel, and there are no errors in the error log, it's completely blank, which is a first too.

This is the site: http://fondelifair.com

Any suggestions for what I may have done and how to fix it?

Thanks.
