Maybe you can help me with this, when we execute the commands by hand everything is ok:**

But when we use Crontab Linux to execute the commands it seems the server variables are differents and causes errors: **

$SERVER =
array(15) {
["SHELL"]=>
string(7) "/bin/sh"

string(25) "name@mydomain.com"
["USER"]=>
string(8) "myuser"

string(1) "1"
["HOME"]=>
string(14) "/home/hostname"
["LOGNAME"]=>
string(8) " myuser"
[""]=>
string(12) "/usr/bin/php"
["PHP_SELF"]=>
string(0) ""
["REQUEST_TIME_FLOAT"]=>
float(1451933701.83)
["REQUEST_TIME"]=>
int(1451933701)
["argv"]=>
array(4) {
[0]=>
string(76) "/home/hostname/public_html/administrator/components/com_csvi/helper/cron.php"
[1]=>
string(18) "--task=maintenance"
[2]=>
string(18) "--addon=virtuemart"
[3]=>
string(20) "--operation=backupvm"
}
["argc"]=>
int(4)
}
