Can't make cronjobs

Hi,

I've got ISPConfig running nicely. But I just needed to make a cronjob.
When I'm creating it, and click "Save" it returns to the cronjob list, but there is nog cronjob listed.

Anyone know what's the problem?

Thanks!

 

Please paste the /var/log/syslog or equivalent during cron jobs save error.

 

Hmm, strange, when I do it two times in a row it's working (well the cronjob is made, waiting to see if it's working).

Thanks, but what's the problem here? Why 2 times?
