Can't Delete/Swap Product Images

-- HikaShop version -- : 3.0.1
-- Joomla version -- : 3.7
-- PHP version -- : 7.1.4

I cannot DELETE product images in Product edit. The 'x' is visible, but clicking on it does nothing.
I also cannot SWAP product images around to set the display order.

I tried this under PHP 5.6, PHP 7.0, and PHP 7.1 -- all showing same result.
So, this is not a suhosin thing (PHP 7.x does not have it).

I have also tried this on several of my Hikashop client websites, so it isn't the template as they are all different.
I have also tried multiple browsers. I have also turned off the firewall software.
None of these worked.

Also installed JQuery Easy, but that isn't working. There are no console errors.

Turned on ERRORS to Development. Got this:

Notice: Undefined variable: uploader_id in /home/aiohealing/public_html/administrator/components/com_hikashop/views/product/tmpl/form_image.php on line 48

Thank you, that fixed it.
