JSON issue with Contact Form 7

[npn]

Our site was targeted by a spambot recently so I made some updates to plugins and enabled heavier spam protection measures.

Even since updating I’ve had issues with the submission process of our contact form.

Checking the Dev Tools Console, it seems to be related to JSON and reCAPTCHA.

This is the error code we get:

Object { code: "invalid_json", message: "The response is not a valid JSON response." }

code: "invalid_json"

message: "The response is not a valid JSON response."

<prototype>: Object { … }

__defineGetter__: function __defineGetter__()

__defineSetter__: function __defineSetter__()
​​
__lookupGetter__: function __lookupGetter__()
​​
__lookupSetter__: function __lookupSetter__()

​​__proto__:

hasOwnProperty: function hasOwnProperty()

isPrototypeOf: function isPrototypeOf()

propertyIsEnumerable: function propertyIsEnumerable()
