Hello, Does your error_log says anything ? I would save the autorep output on a file and see what is in the file when it is running via CGI:

@job_run = `autorep -J my_job_name -w 2>&1 | tee /tmp/autorep.$$.output`;

Maybe apache or your webserver has not the path to autorep program Regards,

PD: Updated from ">" to "| tee" to " 2>&1 | tee"
