My client just purchased this plugin - version 1.10.0 - 2 days ago and sent me the zip file - istraxx_plgvm2_3_quantity_1.10.0.zip
I installed it yesterday and did some testing and things were working fine.
Today I was adding a couple of Custom Fields, attempted to test but got a Joomla error that the page cannot be found.

I went through many things to try and understand what was causing the problem.
I unpublished the custom fields, even deleted them from the products, but that didn't help.
I unpublished the Quantity Discount plugin and everything functioned normally.
How do I get help on that plugin that was purchased from Istraxx?
Apparently, on line 564 there is a depricated code which I found using debug in VM.
