WotLK "502 Bad Gateway" when attempting donation

[rizke]

When I select pay with card I receive a "502 Bad Gateway" error. I have donated before without this issue.

Is this on my end or the payment sites end?

It could be an issue with session cookies going bad. I know something similar can happen with the Forum.
Try manually logging out of the site (using the Log Out button) and logging in again. That should get you new session cookies and solve it, assuming that's the issue. Worth a try anyway.

im getting the same problem, tried the solution you suggested, but didnt work

Then I'm not sure. I tired before my previous reply and the popup is opening just fine for me, so it isn't something with the page or Paymentwall's widget.
Maybe try a different browser. If that's no good either you might have to contact Paymentwall's support.
