This is the best one that I can think off....do you know some great module for do this?
@NexeuzNio
Open the zip file and delete the numbers from the module folder
It is like this: v2.1.43_quantitydiscountpro
And leave it like this: quantitydiscountpro
This is the problem why you get the error when trying to install the module
Intenté lo que dijiste pero el problema persiste.
I have this version, but I don't know if it works in PrestaShop 8
Thank you for the module, I will try to test it in v8.1I have modified the file, so you can try installing it.
Let me know if this version works for you.
