Doesnt Work With MailChimp Connections

Hi

First of I would like to thank you for the amazing plugin you provided for CF 7 this integrates perfectly and works so well if you want to space your fields next to each other. It’s a plugin I have been looking for, for quite some time now and work very well.

I just found a small issue with it if I connect MailChimp extensions to CF 7. As soon as I connect a MailChimp extension I cant submit the form anymore it just hangs and will never submit the Data. As soon as I disconnect the plugin all works fine again. If I look at the console on Chrome I get the following error: “Failed to load resource: the server responded with a status of 500 () : /wp-json/contact-form-7/v1/contact-forms/4/feedback:1”

I have tried numerous fixes from changing the .htaccess file as recommended by most people on Google to resting the perma links but unfortunately none of those fixes work.

To replicate this issue just try and submit the form at the bottom of the page on the link provided.

If you can please advise me on what would be the best solution I would highly appreciate that as for other people whom I’m sure might be struggling with the same issue.

Thanks again for the great plugin and I look forward to your reply.
