No items showing in shop page and Mega Menu

Hello,

on my other website http://www.shopexpeditions.com none of the items display on the product catalog pages. If I go over where the products should be, there are links to products, but they are hidden. This happened after updating to the new version of Highend. What’s causing these problems?

Also, the mega menu works on the home page and Our Story page, but not any other. I also must resolve that.

Exact link of example: http://shopexpeditions.com/product-category/mens/
