Stripe & Square Merchant Glitch on php system

I need someone who works with merchant api's and can solve issues very quickly. Here is what i need fixed on both systems: System 1: Php codeigniter website system called ibilling i bought on codecanyon years ago. Problem 1: stripe merchant - system has worked fine for years but now when someone enters their credit card the screen turns white and nothing happens. no money is transfered or charged, just a white screen Problem 2: Square merchant - this merchant works. For some reason no matter the amount to be charged it will only charge $1. If i put $50 it will only charge $1 on the card and the money does not show in my square account System 2: Problem: This is custom php system with stripe merchant. This is a subscription based payment terminal. For subscriptions there are 2 things and they are: A) startup/ trial one time cost B) Subscription services per month When an invoice is created it will make 2 separate charges at the same time. For some reason i am getting error that says "error missing parameter" and i think the one time charge ID may need to be updated. Thats all thats wrong with these system. If you do this type thing you can probably fix quickly. If you want this job please tell me "I can fix now and I work with stripe merchant and square merchant". I need this fixed right now so please know what you are doing.
