Pardon intrusion ...
+1 for NOT running PHP 8.X
Do not run wget ... that's been depreciated. Or so it's been said by a Moodle HQ programmer. However, comments in /admin/cron.php still show wget. Please ignore the comment/suggestion.
cron jobs set up in webmin do work, just can't run them via Webmin to see them work.
That's because webmin is perl.
One way to check .. login to webmin
Look at left column bottom for a > icon - that's terminal.
From the terminal prompt type: which php [ENTER]
That should show a path to php-cli ... something like /usr/bin/php
To check that is php-cli, type and enter this:
/usr/bin/php -v
Response to that command should show in response (php-cli)
using that path issue this command:
/usr/bin/php /home/techskill.co.za/public_html/admin/cli/cron.php
If that full path to php-cli is correct and if the full path to admin/cli/cron.php
is correct it will work. That's what should be entered in the Webmin interface.
