After paying for the membership and receiving the registration key,
I entered it in the VirtueMart Membership Number field.
But the registration on the site
https://extensions.virtuemart.net/ failed and the yellow message did not disappear.
It turned out that the browser gives error
500 when trying to execute the &task=getMemberStatus request.
How to solve this problem?
Call stack attached.
