payment is set up with paypal pro on (plugin)gravity form, which is used to register users and add to database after paying. After successful payment, if user hits back button on browser during session, if it goes back to point when payment is made, it ill charge credit card twice. Not sure how to fix. (thinking simple code of redirect?) or (nocache) open to suggestions.
