Admin customer group link returns 404

[neopixel]

Hi,

I'm trying to set up customer groups in magento for my store but when i click the Customers > Customer Groups link in the admin menu, my system comes back with a 404.

Does anyone know how to fix this?

I'm running Magento CE ver. 1.9.3.1

Thanks in advance.

Hi @neopixel,

There isn't a special need for that part of the Customer module. If the Customers section works, then you'll need to check if the controller (the file) exists:

app/code/core/Mage/Adminhtml/controllers/Customer/GroupController.php

Maybe you are using some 3rd-party module that change something about Customers?
