CRON Errors
You may encounter those errors in your log while inspecting those:
[23-Oct-2016 20:05:24 UTC] PHP Notice: Undefined index: SCRIPT_NAME in /home/username/public_html/cron.php on line 39
[23-Oct-2016 20:05:24 UTC] PHP Notice: Undefined index: SCRIPT_FILENAME in /home/username/public_html/cron.php on line 40
Those errors are fom the framework PHP CRON file.
Why is it happening?
While executing the cron, SCRIPT_NAME and SCRIPT_FILENAME aren't expanded by the system.
Solutions?
It is possible to include environment variables directly from the cron tab.
Global (This approach may naot work on certain OS)
1a) From a terminal, ecit the contab by executing the following command (it must be done from the web server user):
crontab -e
1b) Add the following to the top:
SCRIPT_NAME="cron.php"
SCRIPT_FILENAME="cron.php"
1c) Save and close the editor.
Per cron job (easier and safer to implement)
2) Prepend the following to your cron job:
export SCRIPT_NAME=cron.php; export SCRIPT_FILENAME=cron.php;
Example
*/5 * * * * export SCRIPT_NAME=cron.php; export SCRIPT_FILENAME=cron.php; php ~/public_html/cron.php >/dev/null 2>&1
The error should now be gone following the crontab update.
