Action inactive

Hello,

(sorry google translate is my friend)

I have a problem with the actions.
I have defined the reports, although they appear on the forum.
I also defined the actions to send an email to the administrator when a comment is posted.

Despite a manual cron auccun email arrives. I do not even know if they are sent.

With version 2.x flag, I received many emails.

Do you know provien or concern?

thank you
