What version are you using?
AFAIR, 1.2 places the ion-out*.txt files in your cgi-bin directory (I don't
think it is configurable). In 1.4 you can set the path in your .ionsrc file
but by default it is in the cgi-bin directory. I would guess that the
reason you can't find your ion-out files is that your ION processes do not
have permission to write to your cgi-bin directory. Since we run ION as
user nobody, I had to change permissions on our cgi-bin dir when I was
debugging with 1.2. With 1.4 you can specify a directory which is owned by
nobody and dispense with that hassle.
In general, to track down ION Script issues you can look at your servers
error log, then ion-p output (set in 1.4 in .ionsrc) then the ion-out*.txt
files generated by ion-i. If you are using 1.2, be prepared to receive
little to no debugging information at times. I developed our ION Script
application in 1.2 and found that certain bugs would generate no debug info
at all (I *think* with 1.2 ion-p doesn't do any logging of errors so if your
error occurs there you are left wondering). I wish I could give you more
help but I have suppressed all recollections of that experience. 1.4 is
supposed to be much better.
If you are running apache, default locations for some of these files are as
follows (assuming /usr/local/ install):
/usr/local/apache/cgi-bin/.ionsrc
/usr/local/apache/cgi-bin/ion-out*.txt
/usr/local/apache/logs/error_log <- apache error log
Enjoy!
