Product display in catalog

Hi,

If you go to the Joomla menu manager and edit your menu item, you can change the number of columns under the "products options" tab.
Otherwise, you can also change the layout to "table" instead of "div".

Hi,

In the module that you inserted in the Joomla article on your homepage, you have a "menu" setting under the "products options" tab.
This setting indicates the categories listing menu item the system should use when you click on a category of that module.
You apparently selected an invalid menu item or no menu item in that setting which leads to that problem.

Hi,

There is no link between the fact that the menu you selected has submenus and the errors that you get.
The errors that you get indicates that you've configured images in sub categories of the category you clicked on but that the images selected cannot be found and thus the thumbnails system is not able to generate the thumbnails.
It also seems that you've the "force size" setting turned on in the HikaShop configuration while you didn't enter both a width and a height for the thumbnails size setting.
So you should try turning off that option.

Hi,

Well, that's a categories listing menu item, so of course is displays the sub categories of the current category.
If you want only the products, then you should use a products listing menu item.
There is no option in HikaShop to change the order of the languages.
Regarding the default language of the website, you can change it in the Joomla languages manager.
