Hi HIkashop
i have recently updated a client site to Joomla 3.7 and all seemed to be OK except for the category and product layouts
they have all reverted to single column

despite changing the category to reflect multiple columns i cant seem to get more than one to display

the template is bootstrap compatible

can you help please

i have also tried to reduce the image size to see if that would help - but it does not ;-(

scratch that - i fixed it with

.hikashop_subcategories div.hikashop_category, .hikashop_products_listing div.hikashop_product {
   width: auto;
}
