FTP로 접속해서 파일을 확인해보세요.

/wp-content/plugins/kboard/class/KBoardBuilder.class.php 파일입니다.

아래 코드를 찾아서 "You do not have permission."이라고 된 부분을 변경해보세요.

상황에 따라서 다르기 때문에 하나씩 변경해보세요.

if(!$this->uid && !$this->board->isWriter()){
	if(is_user_logged_in()){
		echo '<script>alert("'.__('You do not have permission.', 'kboard').'");</script>';
		echo "<script>window.location.href='{$url->set('mod', 'list')->toString()}';</script>";
	}
	else{
		$login_url = wp_login_url($_SERVER['REQUEST_URI']);
		echo '<script>alert("'.__('You do not have permission.', 'kboard').'");</script>';
		echo "<script>top.window.location.href='{$login_url}';</script>";
	}
	exit;
}
else if($this->uid && !$this->board->isEditor($content->member_uid)){
	if($this->board->permission_write=='all' && !$content->member_uid){
		if(!$this->board->isConfirm($content->password, $content->uid)){
			$confirm_view = true;
		}
	}
	else{
		if(is_user_logged_in()){
			echo '<script>alert("'.__('You do not have permission.', 'kboard').'");</script>';
			echo "<script>window.location.href='{$url->set('mod', 'list')->toString()}';</script>";
		}
		else{
			$login_url = wp_login_url($_SERVER['REQUEST_URI']);
			echo '<script>alert("'.__('You do not have permission.', 'kboard').'");</script>';
			echo "<script>top.window.location.href='{$login_url}';</script>";
		}
		exit;
	}
}

고맙습니다.
