[Plugin: PayGol] Problem

The plugin ain’t working. It’s just returning the same paygol button after payment and not the hidden content.
I tried fixing it but with my php knowledge it was just like trying to build a rocket.
And i see in the code that the potential client needs first to make an account with and only then he’ll be able to send a SMS. what’s the point of that? It only drives people away instead of converting every single visitor
