Answer 1

Locate the line that the code being used to import jQuery and make sure it shows the following:

JHtml::_('jquery.framework');

Which imports it in noConflict mode, but is also for Joomla 3.x only

Else you can replace it with the following, which will detect if a jQuery library is already being loaded and if not, it will import it.

if (!JFactory::getApplication()->get('jquery'))
{
    JFactory::getApplication()->set('jquery',true);
    JFactory::getDocument()->addScript('http://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js');
}
