Conflict between Ajax Add To Cart and Configurable Product Wholesale Display for Magento 2

Question:

I have an error ‘You need to choose options for your item’ error when you try and add an item to the Cart. 

Answer:

Ajax Add To Cart for Magento 2 version v1.1.5

Configurable Product Wholesale Display for Magento 2 version v.1.1.4
