Issue:
I am using Magento 2 Configurable Product Matrix View ver 1.1.7 on Magento 2.2.9. When I set up the config Show Unit Price = No and Show Tier Price = No, the site does not work anymore.
It gets this error:
1 exception(s):
Exception #0 (Exception): Notice: Underfined offset: 15890 in /app/code/Bss/ConfigurableMatrixView/Plugin/Block/View/Configurable.php on line 395
