Userman is not generating vouchers

Good day,

I have set up a working hotspot with userman and radius authentication.

The issue now is the vouchers.

If I understand correctly there should be a pop up window when you click generate voucher.

When I click it nothing happens.

I tested on a local router, but still the same happens.

Is there something specific one should set up or should it just work?

Thank you.

I Realize this was posted in the incorrect place.

Will post in userman
