The subscribe button is not doing anything when pressed.

Plugin version: 4.10.2; WP version: 6.7.2; PHP version: 8.1

Hello,

I am testing out this plugin on my staging site which uses the Divi theme. I successfully connected my Mailchimp account, customized my form, and then embedded it via shortcode in the body of the linked page. However, when I click Subscribe, there is no response whatsoever and I don’t get any emails. In the Inspect tool console on Firefox, the only error I can see that might be related to this is:

“Uncaught (in promise) null”

but it does not specify anything else.

In the Inspect tool console on Chrome, that same error appears plus another error that might be related:

“Failed to load resource: net::ERR_CONNECTION_CLOSED” from the file “_jb_static/:1”

and this error from an unspecified source as well:

“Uncaught (in promise) Error: A listener indicated an asynchronous response by returning true, but the message channel closed before a response was received”

My staging site’s error logs don’t indicate any errors or warnings related to this either.

Could I please have assistance with figuring out this issue? Thanks!
