System -> Payment Methods -> New -> Hikashop UserPoints Payment Plugin results in error message: 0 Call to a member function display() on null

Please help.

FYI - from a different post regarding the frontend I did add the code below before line 39 and it did not resolve the issue.

$this->categoryType = hikashop_get('type.categorysub');
$this->categoryType->type = 'tax';
$this->categoryType->field = 'category_id';

Thanks for the reply.

The file is in place, and I re-downloaded and installed Hikashop and still have the error.

The points do show up in Hikaserial Pack statistics, so it seems that that part is correct. However the points do not show up in the back-end user profile or the front-end Your Account. The custom field is in place.
Hikashop -> System -> Plugins has all User Point plugin published.

Not sure what else to check. User Points exist in Serial but are not showing up in Hikashop.

Your thoughts?

Thank you.
