Can't add security groups

Hi,

Running 5.x.2.3, PHP 5.2.6, MySQL 5.0.51a.

When I try and add a security group I get the following error...

warning: Missing argument 1 for _uieforum_security_group_form() in /homepages/24/d236848111/htdocs/hrfc/sites/all/modules/uieforum/uieforum.module on line 2336.

The page then displays. I add the security group and on submit I get the following error...

warning: Missing argument 1 for _uieforum_security_group_form() in /homepages/24/d236848111/htdocs/hrfc/sites/all/modules/uieforum/uieforum.module on line 2336.

and I am returned to the UIE forum management page. The group I have tried to add does not display although it is in the f_groups table.

Anyone any ideas whats going on here or a possible fix, something wrong with my configuration ?

Thanks
Keith
