While attempting to diagnose another issue (which I asked about over here), I discovered that the apache 1.3.37 installation on a machine I inherited doesn't log 404 errors to
error_log. I've scoured the config files for
ErrorLog directives, but they're all just the standard 'set a path and (for CustomLog) combined format' type.
It does log other errors normally, such as 'Permission denied', but 404s are silently ignored.
What might be causing this and how can I get the 404s to appear (at least temporarily)?
