Hello Poum,

Thank you for reaching us!

Since we do not know what your setup is, we cannot give you information on what you have to change and do you have to change something at all. Our module is free, so you can easily download it and see what the source is and if you need to modify something.

Let us know if you have additional questions.

Hope this helps!
