BUG – It does not work – GoUrl Paid Memberships Pro

The problem is that every new user that registers, automatically becomes active as if he had paid the membership, without having to pay anything, automatically is assigned in the membership that I select without having to pay

Works perfect until this version 2.0.7 – 2019-05-30

The update made this wonderful extension stop working, the problem is how many thousands of years it takes to launch an update the GOURL developers, because they are usually very slow updating and take days to respond to an e-mail

Any solution to modify any file that generates this problem?
