Hi
I have replied to you in a private reply, but it seems not visible to you. Just reply to you again:
@floomingsl
I have debugged some issues, although now API can be connected, App still can’t get the consumer key. I guess it’s the server issue. Because I have also tested again on another hosting, it worked.
So, unfortunately, I can’t fix this issue on your server. You can ask for a refund via Envato, I will confirm the refund request.
I’m sorry about this issue.
