Some pages the products are standing left, on the right and some at the middle

Hi,

It's not a bug of HikaShop.
The problem comes from several things:
- the height of each product box is not the same because of the content in them.
- the template you're using has some view overrides for the products listing (to get the nice effects you see) for example. However, these are based from an old version of HikaShop. Because of that, even if you activate the "height consistency" setting of the products listing, the height will still be different between the boxes.

There are several ways you could fix that:
- Add some CSS to your template to force the height of the boxes.
body .hikashop_products .hikashop_product {
height: 380px !important;
margin-left: 0 !important;
}
- upload images with the same ratio height/width
- turn on the "force size" setting of the HikaShop configuration so that HikaShop would generate thumbnails with the same size for all the images.
