If you are having an issue with the NOT working cron, you can do the following to check it.

Check if crond is working

# service crond status
crond (pid  1386) is running...

You can also check cron log file and see if cron script is executed

tail -n 20 /var/log/cron

If your cron script is executed in the log, then you can check the following
Login as root on the server, and then execute cron script as a user

#su USERNAME -s /bin/bash

Check that you will execute script as a user


Now you are ready to run your cron script manually, just execute your cron script, example:

/usr/local/bin/php /home/USERNAME/public_html/cron.php

You will see if you have any issue and you can do a quick fix.

Most common issues
– if file is executed via shell and not via http:// then the most common issue is that file needs to have execute permissions
You can try to fix that by using this command: chmod +x FILENAME
