Fix Elementor Form Submission Issue

My Elementor Pro Forms have stopped submitting altogether—no spinner, no confirmation, nothing. I have already cleared cache and cookies, yet the problem persists.

I need you to jump in, pinpoint whatever is blocking the AJAX request or server-side hand-off, and restore normal submission behaviour. If the fix involves plugin conflicts, misconfigured reCAPTCHA, PHP errors, or hosting restrictions, please document exactly what you changed so I can replicate it on staging and future sites.

Deliverables
• Form submits successfully and displays the chosen success message/redirect
• Test email reaches inbox (using the existing notification settings)
• Brief report of root cause and steps taken

I will provide admin and FTP access as soon as we start so you can test in real time.
