I see various other questions relating to issues with the RSS Import module but none that answer my question. I am trying to automatically import RSS feeds using a cron job but for some reason it is not working. I've verified with my host tech support that the cron function is working and that the path I am using to the import.php file is correct, but for some reason the file isn't running. I'm not experienced with the command line interface and am using my host's account control panel to set up the cron job. Does anyone have any suggestions? When I access the /import.php file via a browser nothing happens. As far as I can tell it is the correct import.php file I've seen in various threads/blogs offering instructions on running the RSS import module with a cron job.
