I removed all of the files from the web server when I discovered the database connection was broken (loads of error messages being generated, not good PR and possible security risk). I put a temporary blank index.html page up.
I am in process of sorting other issues (e.g. unable to send remote emails (the protocol or something changed/broke without warning - no reply from Jason to my email about it yet). I don't use web mail for several reasons.
So, unfortunately, the site will remain blank while in the process of resolving things and I attend to business otherwise.
Thanks to everyone for their help and advice - this thread started to just get some info!
