designers and brand page

Have a look here
https://quadlayers.com/documentation/perfect-woocommerce-brands/shortcodes/

your code is not ok: [product_brand_list show_empty_brands=”true”]

try this: [pwb-carousel items=”10″ items_to_show=”5″ items_to_scroll=”1″ image_size=”thumbnail” autoplay=”true” hide_empty=”true” title_position=”after”]

i try to insert this code [pwb-all-brands per_page=”10″ image_size=”thumbnail” hide_empty=”true” order_by=”name” order=”ASC” title_position=”before”] but there is not images visible on the page

Looks like you don’t have any images linked to the brands.
