Website not updating

Today I experienced some troubles with my DH wordpress site - apache server was running PHP files as the wrong user, so i couldn’t log in or view the site at all.

That was “fixed” quickly. But, ever since then my site no longer updates, as if there’s some kind of permanent cache on the home page. I’ve removed all caching plugins, deleted cache files, have seen new posts show up in my rss feed, see new comments on single posts, deleted index.html, and even tried changing my blog theme.

The result? Individual pages and individual posts updated, but dreamhost still serves the same homepage even with a different theme loaded.

I’m on ps. any idea on this, maybe a server reboot?
