ISPManager Cron error 255

Hello,

ISPManager give me this error with cron backup task, if I run the command on console I don't receive any error, but if I run the command with ISPmanager cron task I got it:

Backup ERROR (global block): Manager function cannot be called internally
Exited with return code = 255

@weekly /usr/local/ispmgr/sbin/pbackup backup 1

'pbackup' execution is restricted in the module "Scheduler (cron)".

This is not an error, it's an ISPmanager limitation. Run the backup task with shell.
