Thank you for your patience. I see the Javascript error is gone now and the popup is still not working.
It's less clear what the problem is now, but I *think* it's that the Bootstrap JS is being loaded twice on the page (and different versions). Here are the 2 inclusions I see in the HTML:
<script src="/media/jui/js/bootstrap.min.js?172b1115b5b805b293e7c9f64fe4fc9a" type="text/javascript"></script>
<script src="/templates/trg/js/bootstrap.min.js" type="text/javascript"></script>
The first one is the standard Joomla version of the Bootstrap JS that the SCLogin module expects. If you view the source, it has this comment:
*!
* Bootstrap.js by @fat & @mdo
* Copyright 2012 Twitter, Inc.
* www.apache.org/licenses/LICENSE-2.0.txt
*
* Custom version for Joomla!
*/
The 2nd file is v3.3.1 of Bootstrap which, while it should be fine on it's own, may be conflicting with the first.
Would it be possible to (temporarily) disable the bootstrap.js file from your template to test if the modal works? If so, test if other functionality breaks.. and then we can go from there to figure out a course of action.
Thanks,
Alex
