Website gone? Blank?

I might be totally wrong here but I’m asking on behalf of the person that runs the site, who’s technically not as savvy. Anyhow, we have just noticed that our site (kennethlawrence.org) is simply blank. Even when I try the admin URL and try to log on, nothing appears. I contacted the hosting service (Bluehost) as I thought it might be an issue on their end, but they referred me back to WordPress, stating everything is okay on their side.

Could anyone here help me, respectively guide me to resources that might help me figure this out? Unfortunately I don’t know what version of WP the site runs, since I obviously can’t log in.

Thank sooo much advance! Answers/advice appreciated.
