Hi,
your theme is a mess....
You have 3 jquery versions in your header, and you try to use a jquery script BEFORE it's declared:
<script type="text/javascript">
jQuery.noConflict();
jQuery(document).ready(function($){
$(".forumbit_subforums").each(function () {
if($(this).length){
$(this).parents(".rowbit").find("a[data-subforum]").addClass("smalltext").attr("data-subforum", "true");
}
});
});
</script>
Try to put this AFTER this:
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
The thankyoulike plugin have some parts missing, the form of the login has IDs duplicated, etc. etc.
But let's go to the Breadcrumb problem:
Admin Control Panel > Templates & Style (Tab) > Themes > YOUR THEME > theme.css > Edit Stylesheet: Advanced Mode (Tab)
Look for:
.breadcrumb .crust .arrow span {
border: 23px solid transparent;
border-right: 1px none #000;
border-left-color: #0d4c41;
display: block;
position: absolute;
left: -23px;
top: -23px;
z-index: 51;
white-space: nowrap;
overflow: hidden;
text-indent: 9999px;
height: 0;
transition: all .5s ease;
}
And change it for:
.breadcrumb .crust .arrow span {
border: 23px solid transparent;
border-right: 1px none #000;
border-left-color: #0d4c41;
display: block;
position: absolute;
left: -23px;
top: -23px;
z-index: 51;
white-space: nowrap;
overflow: hidden;
text-indent: -9999px;
height: 0;
transition: all .5s ease;
}
Now the breadcrumb is working.
