on some server (e.g. virtual server at host europe) the cronjob feature does not allow to set a command, but a path to a file to execute.
following two workaround
1. shell script
create a file
cron-lynx.sh
with following content
#!/bin/shlynx -dump http://[your-website-cron-url] > /dev/null
and replace [your-website-cron-url] with the URL to the cron script to execute.
in your server admin panel set up the cronjob to call this new file:
<root-path>/cron-lynx.sh
2. php wrapper
create a file
helpdesk/scripts/cronjobwrapper.php
with following content
#!/usr/local/bin/php<?phpinclude('jobs.php');?>
in your server admin panel set up the cronjob to call this new file:
<root-path>/cronjobwrapper.php
