My reCaptcha is working nice on contact form (Formidable Form) at first. But it fails to be loaded after using this plugin (pie register). However the pie register forms (ex. login, registration form) are ok but the contact form failed. I wonder there is any conflict but there is no warning or error displayed on console.
Sorry for any inconvenience. We tested the 2 plugins together and found that both are not compatible to be used together. We will further dig in to see if the conflict can be resolved in future releases.
