Hi,
Do you have a view override for the view "product | listing" ?
We fixed something in HikaShop 2.3.2 in the listing view for the "group by category" option.
You should have this part of code in the view
} else if(!empty($this->rows) && !empty($this->categories)) {
if(!$this->module) echo $mainInfo;
$allrows = $this->rows;
The variable $mainInfo contains the HTML with the image and the description.
It wasn't display in the mode "group by category", but the added line should fix the problem.
Regards,
