I believe it's about element with the same ID name "wrap" used in both template and module. You will have to rename it in template or in module.
Also, could be a conflict between module and a script used in template. Strange, but there are no javascript errors shown.
Please edit index.php of template and find this part:
Code:
<script type="text/javascript" src="/components/com_gantry/js/gantry-totop.js"></script>
<script type="text/javascript" src="/components/com_gantry/js/gantry-buildspans.js"></script>
<script type="text/javascript" src="/components/com_gantry/js/gantry-smartload.js"></script>
<script type="text/javascript">
window.addEvent('domready', function() {
var modules = ['rt-block'];
var header = ['h3','h2','h1'];
GantryBuildSpans(modules, header);
});
window.addEvent('domready', function() {new GantrySmartLoad({'offset': {'x': 200, 'y': 200}, 'placeholder': '/templates/rt_grunge_j15/images/blank.gif', 'exclusion': ['ul.menutop span.image']}); });
</script>
You can try disabling the <script> lines one by one to see when the module will start working correctly. Once you find the error, remove that line from template, but then check if the rest of your site is working properly.
