Landing Page is there. Nothing else works

I am not sure where to begin. I have made slight editing changes previously with success. We had a hacker put up some blog posts. My boss disabled the blog – I was told. I can see our info on the pages in admin, but nothing is actually displayed on the site. I don’t know if it is related to the hack, what my boss did, both or neither.

I’m not a coder. I did deactivate and reactive the plugins. I ran some updates without making any progress.

The page I need help with: [log in to see the link]
