Rails app running under Phusion Passenger shows only a white screen

Question

I had posted another question earlier about deployment with Passenger. That problem turned out to be a permissions issue, and I fixed it by running chmod on the www folder recursively.

Now, I don't get the Phusion error page, but I get a white screen of death. The Rails logs show no error messages, and I cannot figure out what is going down here.

EDIT: These come from the error log...at least I think they do. All error.logs have been gzipped for whatever reason. The status code of the page is 500 Internal Server Error.

SQLite3::CantOpenException (unable to open database file):

EDIT2: FInally got some error output from the server. :-P

Answer 1

Your error log is probably being gzipped by the log rotation daemon. It's a pretty standard component of most servers.

Anyway, you're getting a white page because, as the error says, there's something wrong with your database file, probably another permission problem. Fix it and it should work.
