I have a lot of clients using GoCardless with WHMCS however I've had to upgrade to PHP7 and use a newer payment module.
The new payment module doesn't seem to work with the old one and isn't showing where the errors are or why it isn't taking payments or marking invoices as paid.
I've posted on this forum (see last post) for help but not yet received a reply so I'm hoping someone may be able to help a bit quicker by setting up a freelancer project instead:

I need someone that can work with payment APIs and whmcs/gocardless as well as being well versed with php and mysql to fix this please. I don't have much budget as if this can't be done cheaply I may as well slowly move all clients to use a different payment method but I would like this to work for convenience.
