G’day Meg,
I’m running the latest Gravity Forms 2.4.17 in my test environment, with no problems seen across any of my plugins including DPS PxPay (Windcave).
On your test environment, are you running in the sandbox or against the live gateway? If sandbox, can you try the live gateway to see whether the live account has a problem? It might be an issue with the account.
Please also enable logging in Gravity Forms, and enable logging for the add-on so that we can see what is being logged. It might help identify what is going on.

Thanks for your speedy reply Ross!
It is working now – I rolled the live site back to the previous version and then updated it again and it works just fine.
Oh good, the old “something stuck in the pipes” thing again 🙂
Glad you got it sorted with a reinstall.
cheers,
Ross
