This option is pointless, because it only create links like
member.php?uid=1 or
user-1.html. This is not the way a plugin developer should create links (manually!!!).
Here is an example:
Replace this:
if($mybb->settings['gseolp'] == "0")
{
$lastposterlink ='<td><img src="images/last/username.png" style="vertical-align: middle;"><a target="_blank" href="'.$mybb->settings['bburl'].'/member.php?action=profile&uid='.$thread['lastposteruid'].'">'.$thread['lastposter'].'</a></td>';
}
else
{
$lastposterlink ='<td><img src="images/last/username.png" style="vertical-align: middle;"><a target="_blank" href="'.$mybb->settings['bburl'].'/user-'.$thread['lastposteruid'].'.html">'.$thread['lastposter'].'</a></td>';
}
With this:
$lastposterlink ='<td><img src="images/last/username.png" style="vertical-align: middle;">'.build_profile_link($thread['lastposter'], $thread['lastposteruid']).'</td>';
The MyBB function build_profile_link() does all the work for you. I repeat:
You should use functions like build_profile_link(), get_post_link() and get_thread_link() to build links.
