@Daresh Seeing as you might have worked with the module in the past I will dare ask.
I finally have everything installed regarding the module but I have 2 problems:
1. When I have the debug mode set to ON, the following happens:
-> I create separate combinations for 1 product
-> Iif I visit product page and I get the following error, please see first part of the attached image
-> When this mode is ON I can update the product
2. When I have debug mode set to OFF
-> I cannot update the prodcut anymore
-> I get errors in the requests (please see last part of the image, the errors in dev tools part)
-> I can visit the product page
Any idea what might cause this behavior?
