Hello,
Thank you for the credentials.
I was able to see that you're not using the "category explorer" and that your issue is related to a patch I made in order to fix the pagination, but should be conditioned with the category explorer.
In the file "components/com_hikamarket/views/productmarket/view.html.php" please replace
if($cid != (int)$app->getUserState(HIKAMARKET_COMPONENT.'.product.listing_cid')) {
By
if($category_explorer && $cid != (int)$app->getUserState(HIKAMARKET_COMPONENT.'.product.listing_cid')) {
And it will fix your issue.
That patch will be include in the next release.
Regards,
