Not working with LiteCart 2.6

Installation with LiteCart 2.6.0 doesn't work.  
On editing a product, the page does not draw properly and shows the error: Fatal error: Undefined constant "DB_TABLE_PRODUCTS_OPTIONS_VALUES" in ~/vmods/.cache/hcadmin-catalog.app-edit_product.inc.php (Line 1685)

It appears with LiteCart 2.6.0 the database wrapper is not working the same way (in preparation for LiteCart v 3.0).
Can this mod be updated to work with v 2.6+ please?
Or maybe that's not the reason at all, but it causes the error noted above, anyway.

The developer has made an update to support v 2.6 and it is now working.
