It’s possible this is from wpcli; my hosting provider is attempting to setup items for me and troubleshoot speed issues, and is unable to due to this stacktrace. It would be reasonable to assume they are using wpcli.

I have unable to find other earlier or PHP errors related, but I was able to get a full stacktrace:

No, it’s not something different. That bug in your code happens after Paypal has been successfully charged, and the Forminator code tries to validate the response amount from PayPal of what was charged vs what it expects.
Paypal was successful, but the math code in Forminator is screwing up rounding somewhere, resulting in an error being thrown saying it was an invalid amount even though PayPal did charge the customer.
