Website Not Coming Up - Bootstrap Error

I was building my website on my Mac. It was close to being done and almost ready for migration to a real server. But I can't access the local site anymore. The site comes up with a bootstrap error page. The Web Services on the Mac are running. I cleared the data in the cache tables in the PostgreSQL database. Nothing is working. I've even tried trying to force it to provide an error code as described in others' posts, but have gotten no success. The updated code doesn't seem to trigger anything. The website just comes back with the bootstrap error page with my updated code in it. Please help. I've pasted what I'm getting when accessing the site below.
