I got this working in 4.2.3 but would have liked it without the pricing. Picky picky I know.
I removed
Code:
<br />
<font style="color:grey">{$lng.lbl_our_price}:</font> <font style="color:red">{include file="currency.tpl" value=$product_links[cat_num].price}</font>
{if $product.taxes}
{include file="customer/main/taxed_price.tpl"
taxes=$product.taxes}
price code and lost all the navigation and menus!
I made a work around by commenting it out, but would be curious to know why this happened. Anybody can tell?
