The error involves the teacher default image. Is there a drop down for that on the screen below the error?
I think you are mistaken in your other assertions.
#1 the documentation is here:
www.joomlabiblestudy.org/docs/section/5-user-guide-61x.html
While there is nothing specific on installation, most of what you need to use the component is there. Installation normally does not need anything special from you.
#2 I'm a little concerned that you would say we are not helpful on errors. The volunteers that have written and support this component are very responsive. We cannot necessarily fix every error - and often it is something in the configuration of the users web site and not the component.
We consider this a work of ministry and no one gets paid for their time or talents.
This is the code surrounding the error:
$studypath = JPATH_SITE.'/images/'.$params->get('teachers_imagefolder', 'stories');
$fileList = JFolder::files($studypath);
foreach($fileList as $key=>$value)
{
$folderfinal1 = new JObject();
$folderfinal1->value = $value;
$folderfinal1->id = $key;
if (strtolower($folderfinal1->value) == 'index.html') { unset($folderfinal1->value); unset($folderfinal1->key);}
else {$folderfinal5[] = $folderfinal1;}
}
array_unshift($folderfinal5, JHTML::_('select.option', '0', '- '.JText::_('No Image').' -', 'value', 'value'));
$lists['teacher'] = JHTML::_('select.genericlist', $folderfinal5, 'teacher', 'class="inputbox"', 'value', 'value', $admin->teacher );
The component is looking for a folder that is under the /images folder - either the parameter you have set for the teachers image folder (from the drop down above on the admin screen) or for /images/stories. Perhaps you don't have an images/stories folder and haven't set the teachers image folder in the component.
Could be one idea anyway.
