@Djapeto:
1. There is missing Featured Header image. If you don’t want you can disable it or add your own image from “Appearance => Theme Options => Featured Header Image Options”
2. Can you try adding in the following script in “Appearance => Theme Options => Webmaster Tools => Header and Footer Codes => Code to display on Footer”
<script type="text/javascript">
// Open menu on first tap on touch devices.
jQuery(document).ready(function () {
jQuery(".menu-item").has("ul").children("a").attr("aria-haspopup", "true");
});
</script>
