Hi,
When we first created HikaShop, we had products listing displayed as modules at the end of the categories listing menu items, so that you could configure the way the categories listing would display in the settings page of the menu item, and how the products listing would display in the settings page of the module.
And it was actually possible to link several several products listing module to one categories listing menu item.
Since HikaShop 2.5, we've changed that system to make it simpler. For categories listing menu items, you get both sets of settings in different tabs of the menu item and there is no module attached to the menu item anymore.
And the system just fake a module being there for the settings of the products listing.
So you can't configure several modules under one menu item anymore.
That means that you shouldn't be able to configure that anymore on your HikaShop.
However, we had to be able to keep the system backward compatible for two reasons:
- for people on Joomla 1.5 and 2.5, the system still works the old way as we didn't want to put in the extra hours to develop something no one would use/need (people new to HikaShop would be on Joomla 3, and people on Joomla 2.5 or 1.5, were already familiar with the old way of doing it).
- when you were updating from an old version of HikaShop your menu items would still be configured the old way and thus they still had to display properly after the update.
So I suspects this is a menu item coming from an old version of HikaShop or Joomla, and I would recommend you to create a new menu item of the type HikaShop categories listing. That should prevent you from having the same problem with that menu item and then swap the two menu items so that you use the new one instead of the old one.
