I can't tell if you mean to say that 1) there are no files under the
error_logs dir or that 2) you see a file but it is empty.

 1) Make sure your path is correct.  Check the output of
sys:get_status(error_logger).  You should see log_mf_h under the installed
handlers.

2) There should be two files: 1 and index.  These files are in binary (at
least, 1 should be).  In order to read them you use the report browser tool
(rb).
