why don't you go back to a stable release (2.2 perhaps) if you are not comfortable with debugging and fixing errors yourself? I also wouldn't advise on using daily builds.

I already brought this to willrs attention the problems with silverstripe daily build and his forums. He seems to be very sure that there shouldn't be any problems.

i fixed the Forum Member-Register Bug:

i took the constructor from stable forum version and put it into

forum/code/ForumMemberProfile.php :

...
class ForumMemberProfile extends Page_Controller {

public $URLSegment = "ForumMemberProfile";

function __construct() {
return parent::__construct(null);
}

...
