Hi,
In the file "administrator/components/com_hikamarket/helpers/helper.php" please replace in the function "processFilters"
if(empty($orderingAccept) || in_array($t.'.', $orderingAccept) || in_array($this->pageInfo->filter->order->value, $orderingAccept))
$order = ' ORDER BY '.$this->pageInfo->filter->order->value.' '.strtoupper($this->pageInfo->filter->order->dir);
By
$dir = strtolower($this->pageInfo->filter->order->dir);
if(!in_array($dir, array('asc', 'desc')))
$this->pageInfo->filter->order->dir = 'ASC';
if(empty($orderingAccept) || in_array($t.'.', $orderingAccept) || in_array($this->pageInfo->filter->order->value, $orderingAccept))
$order = ' ORDER BY '.$this->pageInfo->filter->order->value.' '.strtoupper($this->pageInfo->filter->order->dir);
It will avoid to insert an "inherit" as the value of the ordering.
Now I don't understand why you have that error because there is check in the view in order to replace the "inherit" by "ASC" ; I tried to reproduce your issue but I couldn't. That's why the patch for the helper will be a good solution.
Regards,
