Cronjob error


I just moved from cPanel to virtualmin.
I have was able to install whmcs and upgrade virtualmin php verison to 7.1. I have also managed to install ioncube for php 7.1
Well, all seems working fine except the cronjob is not running correctly.

I hope you guys can help me with it.

I set up my cronjob for WHMCS as usual from Webmin -> systems -> Scheduled Cron Jobs.

The cronjob runs once per day. When I hit save and run I got those errors with this command /home/username/whmcs_crons/cron.php:
/home/username/whmcs_crons/cron.php: line 1: syntax error near unexpected token <' /home/username/whmcs_crons/cron.php: line 1: <?php //ICB0 56:0 71:3c30 ?><?php //00ee8’

I used this command in cPanel */5 * * * * php -q /home/username/whmcs_crons/cron.php and it worked great but not in virtualmin.

If I have this command: php -q /home/cheapseovps/whmcs_crons/cron.php
The output error:
Failed loading /usr/lib64/php/modules/ /usr/lib64/php/modules/ cannot open shared object file: No such file or directory

Any suggestions please?

Thank you
