Mailchimp API error: 404 Not Found. Resource Not Found.

Hello Dear Team,

I am trying to create a newsletter for my website https://knownandlesserknowntemples.com. The form ID for this form is [mc4wp_form id=”763″].

However this Mailchimp form page does not give me an option to enter any name. It only gives the option to enter an email address. Please click on the link below.

When I am trying to subscribe from the form builder page it gives me an error. Please find the link to the error message below.

Unfortunately, I am not well versed with API and I am new to Mailchimp. I have tried to generate the API a few times, disabled old API’s, followed few troubleshooting steps like deleting cache files, however, nothing works.

The error logs are as follows.
“[2020-03-18 12:02:17] ERROR: Form 763 > Mailchimp API error: 404 Not Found. Resource Not Found. The requested resource could not be found.
