If I navigate to My Account - Settings - Referrals, I am unable to add/modify my referral details. I get the same issue regardless which store I try. I tried logging out and back in and still no luck.
The request returns a 403 if that is of use to anyone.
Is it just my account or are others having the same issue?
There's a permission problem on our end and I've patched it up. Please check whether it has been fixed.
