The custom template was actually developed by one of our former team members and he didn't include the share or teacher information.
If you want, try to experiment by copying this code (out of the studydetails main template) into this file:
/site/components/com_biblestudy/views/studydetails/tmpl/default_custom.php starting at line 41
<?php //Social Networking begins here
if ($this->admin_params->get('socialnetworking')> 0)
{ ?>
<div id="bsms_share">
<?php
$social = getShare($this->detailslink, $row, $params, $this->admin_params);
echo $social;
?>
</div>
<?php } //End Social Networking ?>
<table><tr><td>
<?php if ($params->get('show_teacher_view') > 0)
{ ?>
<?php
$teacher_call = JView::loadHelper('teacher');
$teacher = getTeacher($params, $row->teacher_id, $this->admin_params);
echo $teacher;
echo '</td><td>';
}?>
<?php
if ($params->get('title_line_1') + $params->get('title_line_2') > 0)
{
$title_call = JView::loadHelper('title');
$title = getTitle($params, $row, $this->admin_params, $this->template);
echo $title;
}?>
</td></tr></table>
</div>
Put it right BEFORE this code:
$details = getStudyExp($row, $params, $admin_params, $this->template);
See what happens and let us know. Perhaps we can make this a part of 7.0 too.
