I have a custom coded slider on my site. I didn't code the slider because I don't know JavaScript. However, I did figure out where the problem is coming from. Here's the code snippet that is causing the issue

$.fn.infiniteCarousel = function () {

function repeat(str, num) {
return new Array( num + 1 ).join( str );
}

return this.each(function () {
var $wrapper = $('> div', this).css('overflow', 'hidden'),
$slider = $wrapper.find('> ul'),
$items = $slider.find('> li'),
$single = $items.filter(':first'),

singleWidth = $single.outerWidth(),
visible = Math.ceil($wrapper.innerWidth() / singleWidth), // note: doesnt include padding or border
currentPage = 1,
pages = Math.ceil($items.length / visible);


// 1. Pad so that 'visible' number will always be seen, otherwise create empty items
if (($items.length % visible) != 0) {
$slider.append(repeat('<li class="empty" />', visible - ($items.length % visible)));
$items = $slider.find('> li');
}

// 2. Top and tail the list with 'visible' number of items, top has the last section, and tail has the first
$items.filter(':first').before($items.slice(- visible).clone().addClass('cloned'));
$items.filter(':last').after($items.slice(0, visible).clone().addClass('cloned'));
$items = $slider.find('> li'); // reselect

// 3. Set the left position to the first 'real' item
$wrapper.scrollLeft(singleWidth * visible);

// 4. paging function
function gotoPage(page) {
var dir = page < currentPage ? -1 : 1,
n = Math.abs(currentPage - page),
left = singleWidth * dir * visible * n;

$wrapper.filter(':not(:animated)').animate({
scrollLeft : '+=' + left
}, 500, function () {
if (page == 0) {
$wrapper.scrollLeft(singleWidth * visible * pages);
page = pages;
} else if (page > pages) {
$wrapper.scrollLeft(singleWidth * visible);
// reset back to start position
page = 1;
}

currentPage = page;
});

return false;
}

$wrapper.after('<a class="arrow back">&nbsp;</a><a class="arrow forward">&nbsp;</a>');

// 5. Bind to the forward and back buttons
$('a.back', this).click(function () {
return gotoPage(currentPage - 1);
});

$('a.forward', this).click(function () {
return gotoPage(currentPage + 1);
});

// create a public interface to move to a specific page
$(this).bind('goto', function (event, page) {
gotoPage(page);
});
});
};

$(document).ready(function () {
$('.infiniteCarousel').infiniteCarousel();
});

I don't know what to do to get the edit bar to show. Any help will be highly appreciated.

Thanks
