Tip a frend error (3.9.3 after upgrate from 3.9.1)

Thursday 22 November 2007 1:06:41 pm

I'm using 3.9.3 version (it's a version after upgrate from 3.9.1).
When a logged user is trying to send a message (using tipafriend) then I have an error:

The message was not sent due to an unknown error. Please notify the site administrator about this error.

eZ debug:
mail() [<a href='function.mail'>function.mail</a>]: Bad parameters to mail() function, mail not sent. in /lib/ezutils/classes/ezsendmailtransport.php on line 88

What is the reason of that?
