error when I create new category

Hi.

I have error message when I add new category.
I have no clue how to fix this.
I'd like to get some valuable advise before I do clean opencart install, so please help me.

opencart version : 2.0.3.1

'source': function(request, response) { $.ajax({ url: 'index.php?route=catalog/category/autocomplete&token=f0fdcb812ba66e7548fdfcf369c9d14b&filter_name=' + encodeURIComponent(request), dataType: 'json', success: function(json) { json.unshift({ category_id: 0, name: ' --- None --- ' }); response($.map(json, function(item) { return { label: item['name'], value: item['category_id'] } })); } }); }, 'select': function(item) { $('input[name=\'path\']').val(item['label']); $('input[name=\'parent_id\']').val(item['value']); } }); //-->

Thanks
