Question Problem with creating group

[laudemort]

Hi.
I have big problem with group creating on my forum, the problem is:

Zend_Db_Statement_Mysqli_Exception: Mysqli statement execute error : Field 'staff_list' doesn't have a default value - library/Zend/Db/Statement/Mysqli.php:214  
 Stack Trace #0 **/public_html/library/Zend/Db/Statement.php(297): Zend_Db_Statement_Mysqli->_execute(Array)

#9 **/public_html/index.php(13): XenForo_FrontController->run()
#10 {main}

do I have to do something, or is there a bug in the code?

Does you have new install or just upgrade add-on?
Also have you comfort with manual run an query?
