#4 Log file or statisic page of work results

[Murz]

I have installed httpbl on my apache (Debian Lenny) and, I think, it works. But I can't see any statistics or log file with his works results.
I set the
HTTPBLLogDir /path/to/httpbl/logs/dir
and give 777 permissions to this folder.
But I don't see any logs in this page!

If I go to http://127.0.0.1/httpbl_diagnostics I see the empty httpbl_diagnostics_test.txt file in this folder.
How can I view the statistics of work?
