Unmount category

Hi, I get this error when I try use the unmount button in the catalog.

Notice: Undefined variable: category in ~/admin/catalog.app/catalog.inc.php (Line 144)
Fatal error: Call to a member function load() on a non-object in /home/timint/domains/demo.litecart.net/public_html/admin/catalog.app/catalog.inc.php on line 144

Confirmed. In admin/catalog.app/catalog.inc.php

Find

$category->load($category_id);

Replace with

$category = new ctrl_category($category_id);

Fixed in the next release.
