Display categories instead of menu

Then, instead of creating a menu of the type listing category, you should go in the menu Display->Content modules and click on new, then set it to display categories, as a list, all sub elements, published, not synchronized, on 1 column, and save. Then, you should check that it's set in a position which exists in your template via the module manager and normally it should display a list of all your categories and upon clicking on one it should display the list of products inside that category.

What link do you have for the product ?

We need more information to help you.

I mean: what is the URL you have in your browser when you get that error ?

Could you give us the real link so that we can have a look directly ? (you can send the URL via our contact form if you don't want to put it here)

That's because there is no menu attached to your module in the hikashop options of your module.
Normally, it should be created automatically by HikaShop.Apparently it wasn't on your website for some reason.
What you should do is create a new main menu via the menu manager and in it, create a new menu item of the type hikashop category listing.
Then, go in the menu Display->Contents modules, edit your module's hikashop options and set the menu option to that menu.

Could you do a screenshot of the hikashop options of your "nwe cat list" module ? Looking at the URLs of the categories, the "menu" parameter is set to none which shouldn't be the case.

That sounds good. Could you give a back end access to your website so that we can check the other parameters ?

Hi,

Yes, we got your email. The problem seems to come from the SEF option in the joomla configuration on your website. After turning it off, it works properly...
