Which OS? Which version of CVSweb? Can you post of a diff between
cvsweb.conf.dist and your cvsweb.conf?
Uncommenting '$DEBUG = 1;' in cvsweb.conf will cause STDERR to be sent
to your web server error log instead of /dev/null. However, for the
rcsdiff command STDERR is sent to STDOUT by default so you are already
seeing any errors in your web browser.
Attached is a patch for CVSweb 3.0.6 which will print out the rcsdiff
command used. It should print out at the top of the diff output.
One final note:
When testing from the command-line be sure to run the command as the web
server user (i.e., 'sudo -u www rcsdiff ...').
