Cronmanager does not work when you run a URL with CURL

[RobertoM]

Hello people! , im new here, I hope at some point contribute to the community, im a question.

First: my system

Ubuntu Server x64

Version 10.04 LTS

Plesk 10 With the latest update

when I try to run an application in PHP with Curl every 1 minute, if I do it by hand

SSH console ->

crontab -e

* / 1 * * * * /usr/bin/curl http://site.com/script.php

works well, but since the panel does not work , in the logs is trying to run them, but does nothing.

I noticed in /var/spool/cron/crontabs/domainuser, is ok, is configured as in panel

* / 1 * * * * /usr/bin/curl http://site.com/script.php

run using the full path of php does not work with the full path to curl either, also tried lynx and wget options but no luck

any idea?

thanks in advance!!
