MyBB Community Forums

i am getting this [Moderated by Guests] no color no link of profile. any help ?

Yes, that's the issue with that plugin. I've edited its required part and also submitted on its review page. Here's how to correct it;

Since many users are facing the issue that when they Install this plugin, then their Moderated By: "Some Username" becomes Moderated By: Guests

So here is how to resolve this issue;
Alright, Open plugin file and find;

function usernamestyle_build_forumbits_forum(&$forum)
{
    global $db, $mybb, $lang, $templates, $moderatorcache, $modlistsetting;
    
    // Moderator column is not off
    $mybb->settings['modlist'] = $modlistsetting;
    
    if($mybb->settings['modlist'] != 0)
    {
        $moderators = "";
        $donemoderators = array();
        $parentlist = explode(",", $forum['parentlist']);
        
        foreach($parentlist as $fid)
        {
            if(is_array($moderatorcache[$fid]))
            {
                foreach($moderatorcache[$fid] as $moderator)
                {
                    if(in_array($moderator['uid'], $donemoderators))
                    {
                        continue;
                    }
                    
                    $moderator['username'] = format_name($moderator['username'], $moderator['usergroup'], $moderator['displaygroup']);
                    $moderator['profilelink'] = build_profile_link($moderator['username'], $moderator['uid']);
                    
                    $moderators .= $comma;
                    $moderators .= $moderator['profilelink'];
                    
                    $comma = ", ";
                    
                    $donemoderators[] = $moderator['uid'];
                }
            }
        }
        
        $comma = "";
        
        if($moderators)
        {
            eval("\$forum['modlist'] = \"".$templates->get("forumbit_moderators")."\";");
        }
        else
        {
            $forum['modlist'] = "";
        }
    }
    
    // To avoid overwriting by original code segment
    $mybb->settings['modlist'] = 0;
    
    // Format lastposter name
    $query = $db->simple_select("users", "usergroup, displaygroup", "uid = '".$forum['lastposteruid']."'");
    $user = $db->fetch_array($query);
    
    $forum['lastposter'] = format_name($forum['lastposter'], $user['usergroup'], $user['displaygroup']);
} 

and Change it into the following;

function usernamestyle_build_forumbits_forum(&$forum)
{
    global $db, $mybb, $lang, $templates, $moderatorcache, $modlistsetting;
    
    // Moderator column is not off
    $mybb->settings['modlist'] = $modlistsetting;
    
    if($mybb->settings['modlist'] != 0)
    {
        $moderators = "";
        $done_moderators = array(
                    "users" => array(),
                    "groups" => array()
                );
        $parentlistexploded = explode(',', $forum['parentlist']);
        foreach($parentlistexploded as $mfid)
        {
            if(is_array($moderatorcache[$mfid]))
            {
                foreach($moderatorcache[$mfid] as $modtype)
                {
                    foreach($modtype as $moderator)
                    {
                        if($moderator['isgroup'])
                        {
                            if(in_array($moderator['id'], $done_moderators['groups']))
                            {
                                continue;
                            }
                            $moderators .= $comma.htmlspecialchars_uni($moderator['title']);
                            $done_moderators['groups'][] = $moderator['id'];
                        }
                        else
                        {
                            if(in_array($moderator['id'], $done_moderators['users']))
                            {
                                continue;
                            }
                            $moderators .= "{$comma}<a href=\"".get_profile_link($moderator['id'])."\">".format_name(htmlspecialchars_uni($moderator['username']),$moderator['usergroup'],$moderator['displaygroup'])."</a>";
                            $done_moderators['users'][] = $moderator['id'];
                        }
                        $comma = ", ";
                    }
                }
            }
        }
        $comma = "";
        
        if($moderators)
        {
            eval("\$forum['modlist'] = \"".$templates->get("forumbit_moderators")."\";");
        }
        else
        {
            $forum['modlist'] = "";
        }
    }
    
    // To avoid overwriting by original code segment
    $mybb->settings['modlist'] = 0;
    
    // Format lastposter name
    $query = $db->simple_select("users", "usergroup, displaygroup", "uid = '".$forum['lastposteruid']."'");
    $user = $db->fetch_array($query);
    
    $forum['lastposter'] = format_name($forum['lastposter'], $user['usergroup'], $user['displaygroup']);
} 

This should resolve the issue
