All Payment Gate info plugged in but still not working….

Hello- I believe that I emailed you about this before. I hope I get a response on this board.

I have put in all the keys and api and other coding information needed in each of the three payment gateways, wepay, paypal and stripe. I put the information in via the wordpress dashboard.

The payment systems are still not working. I have been told that this is a deprecated version and that is why it is not working. can you help plz.
