Products Not Showing

[Badgernet]

Hello,

 

In the front office there are no products showing after selecting a category. The category images show with the number of products in that category. But nothing else. No product information, images, or Add to Cart etc.

 

In the back office the product images show, but if you try to edit the product it will go no further than information. The same occurs while trying to add a new product.

 

This site has been live for about 6 months and this problem has just started but it could have started with an update.

 

The version I am using is PS V 1.6.1.1. Unfortunately, we cannot just reinstall the program as there has been a lot of customisation done to the site.

 

I am wondering if the client has tried to modify the theme (template). There is a line of coding on the date everything went wrong.

 

If anyone has any idea your reply would be much appreciated.
