Hi,

The block Producttab slider is not configured there, please go to the CMS >> Page, chose ‘nazic_home_page’, select tab ‘Design’, find the code bellow

<block type="core/template" template="sns/blocks/tabs.phtml" name="tabs.slider">
    <action method="setTitle"><title>New Product</title></action>
    <block type="slider/list" name="slider_tab1">
        <action method="setConfig">
            <name>
                <title>Men</title>
                <product_order_by>best_sales</product_order_by>
                <pretext></pretext>
            </name>
        </action>
        <action method="addToParentGroup"><group>custom_tabs</group></action>
    </block>
    <block type="slider/list" name="slider_tab2">
        <action method="setConfig">
            <name>
                <title>Women</title>
                <product_order_by>best_sales</product_order_by>
                <pretext></pretext>
            </name>
        </action>
        <action method="addToParentGroup"><group>custom_tabs</group></action>
    </block>
    <block type="slider/list" name="slider_tab3">
        <action method="setConfig">
            <name>
                <title>Child</title>
                <product_order_by>best_sales</product_order_by>
                <pretext></pretext>
            </name>
        </action>
        <action method="addToParentGroup"><group>custom_tabs</group></action>
    </block>
</block>

replace the code

<title>Child</title>
 <product_order_by>best_sales</product_order_by>
 <pretext></pretext>

By:

<title>Title Category that you want</title>
 <product_category>same Category's ID</product_category>
 <product_order_by>is_featured</product_order_by>
 <pretext></pretext>

The same to the other tabs !

Thanks you,
