I have a form that has worked fine for months. It has recently stopped working. Won’t submit, just shows the spinning icon.

I created a new (default) form and inserted it in a test page. Same problem. So it’s not the form.

I found these instructions for disabling Ajax for form submissions:

Edit contact-form-7/wp-contact-form-7.php

//Change
define( ‘WPCF7_LOAD_JS’, true);

//To

define( ‘WPCF7_LOAD_JS’, false);
//

This fixed the problem, but created a new one: it disabled my “on_sent_ok” redirect upon form submission. Plus, it made the page reload to show the alert. Not very professional.

So where do I go from here? I think I can rule out plugin conflicts and theme problems since no plugins or themes were updated to trigger this. But not sure how to troubleshoot.
