Thank you Soypia
The majority of your errors appear to come from a 'tip-ballon' script looking for images that don't appear to exist in a ../scripts/tip-ballon folder? Is this something you have installed as it is not part of the template?
There is one remaining error which can be amended by removing the following from the bottom of your templates index.php (../templates/j51_calibra/index.php)..
<script type="text/javascript">
var navigation = responsiveNav("#nav", {
animate: true,
transition: 800,
label: "Menu",
insert: "before",
});
</script>
