Whenever I try to click on the Buy Credits button on the page header, I get redirected to My Account main page. I get the same behavior when I click on any credit promotion banner. This has been happening for a few weeks now.

I am using Firefox Quantum, with uBlock Origin and NoScript add-ons (I did try disabling them, but I get the same result). I didn't have this problem a few weeks ago, with those add-ons enabled. Quote
