Hi,
Thanks. I reproduce the problem in my local website and fix it.
A misspelling that I didn't notice.
Please edit the file "administrator/components/com_hikamarket/classes/category.php" and replace
if(!isset($categoy->category_parent_id) && $new) {
By:
if(!isset($category->category_parent_id) && $new) {
It will fix the problem.
