I am working with a Gravity Form for WordPress alongside a Plugin called "Gravity Forms Stripe Add-On". Obviously, the purpose is to process payments using my Stripe account through my WordPress page. After I set up everything, when I try to submit a test payment (or Live for that matter), I keep getting an "Invalid Token ID:" error. Does anyone have a solution for this? I have tried a few different combinations for the settings (AJAX is enabled, both Stripe and Form are set to Test, API keys check successfully). Thanks!
