So i went to the code and here is the strange part. 

I could not find anything in the forum plugin for 13 at all so i have no clue where it gets that number, and nothing in groups for 13 either. 

But there is a function that exists in 3 different files and this is kinda strange. 

When i change this one if fixes the groups pagination (i changed it to 10 and now there are 10 topics showing)

 ow_plugins/forum/components/latest_topics_widget.php            

    public static function getSettingList()

    {

        $settingList = array();

        $settingList['topicCount'] = array(

            'presentation' => self::PRESENTATION_NUMBER,

            'label' => OW::getLanguage()->text('forum', 'cmp_widget_forum_topics_count'),

            'value' => 3

        );

        return $settingList;

    }

the other two the same function name are in groups plugin 

groups_widget.php

user_groups_widget.php

and both set to 3  but they do not appear to change anything... 

Whats up with this?  Also how to change the 13 forum topics to 10?  

Thanks
