I am using JA_Orisite template of joomla2.5 for my client, and unable to load jquery file "//ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.min.js"(needed for menu and article scrollings, etc), This file was being loaded on localhost, when I transfered the site using akeeba backup and recovery process, after installation on server I am unable to load jquery.
Surprisingly, I was having file permission issues on server, once I set 777 to all the files of my site, Jquery file was also working properly.
As the first server is not providing me the expected speed and service, I have transfered the site to other hosting server, which is now giving the same problem of jquery, On this server too I tried to set the permissions to 777, and yet unable to load jquery files.
Rather than importing it from Google, you could always import a local version like so:
<?php
// load jQuery, if not loaded before
if(!JFactory::getApplication()->get('jquery')){
JFactory::getApplication()->set('jquery',true);
$document = JFactory::getDocument();
$document->addScript(JURI::root() . "templates/template_name/js/jquery.js");
}
?>
