Missing Code in My WordPress Site

I paid someone to build a website for me, and now I’m taking a WordPress class to learn how to edit it as needed. However, when I go into the pages to edit them, there’s nothing there, either in text or visual mode. (Each page is there in WordPress, there’s just nothing shown on the pages – no code, nothing.) My teacher looked at it and couldn’t figure it out – she said she’s never seen anything like that before. We looked all over the site and can’t find the code for the pages. It uses a theme called Theme Blvd, or maybe it’s Alyeska by Theme Blvd. The guy who built the site has disappeared; I’ve tried to reach him, but no luck. It’s finewoodmasters.com Can someone please help? What can I do to be able to edit the site? Thank you so much!
