Hello,

Hard to tell, can you switch On the debug mode that may fill your payment log of clues in order to understand what's going on.
Awaiting news from you.

Hello,

1 - Do not post in multiple thread for the same issue.
2 - Please check thread age. Posting in a 4 year old thread is a bit useless.
3 - Read the messages !
