I'm having the same frustration as the original poster. I
have CF8 installed under Apache HTTP Servers (windows) using the
defaults mostly.
In CF7, if I archived a log file, the old file would be
renamed with a numeric suffix (application.log.1,
application.log.2, etc.) in the cf_root/logs subdirectory, and a
new log file would be created. However, in CF8, the archive
function seems to just delete the old file and create a new one.
I've tried searching fot the archived file with no results. I've
also restarted CF; still no archived logs found.
Is there something in the CF8 Administrator that must be
explicitly set to active archiving? The only setting I see is
"Maximum number of archives: 10" which is the default.
