errors are always logged. unless you have a really incompetent sysadmin managing your server (highly doubtful).
the ZC error logging "feature" is a wonderful tool, but there are errors that happen that the ZC error logging does not log for any number of reasons. you need to talk to your hosting company about getting your apache logs... assuming you are running apache. but your hosting company should be able to point to you where your error logs are....
good luck.
