What could be the issue if the Webflow Onboarding Form (Full Page) is showing "Oops! Something went wrong while submitting the form" even though the Form Block setting is set to Method: GET and reCAPTCHA has been turned off and published on the site?

The "Oops! Something went wrong while submitting the form" error in a Webflow form—even with Method set to GET and reCAPTCHA turned off—usually indicates a submission issue at the form processing layer.

1. Webflow Forms Require POST Method

• Webflow’s native form submission system only works with the POST method.
• If you set the Form Block method to GET, Webflow's backend will not handle the submission, resulting in that error message.
• Method: GET is typically used for search forms or when submitting data to an external service that supports GET (e.g., prefiltering a page), not for native form submissions.

2. Check for Custom Action URL

• If your form is trying to submit data elsewhere (e.g., to a third-party server), ensure the external Action URL accepts GET data.
• If no Action attribute is set and Method is GET, Webflow attempts to redirect to the current page with query parameters—but not process the form data automatically.

3. reCAPTCHA Not the Issue

• Having reCAPTCHA off is acceptable. It only blocks spam and isn't required for form submission.
• This is likely not the source of your issue since you’ve disabled it intentionally.

4. Use Native Webflow Form Handling (POST with No Action)

• Set the method back to POST.
• Remove any custom Action URL unless needed for third-party integrations.
• Webflow treats forms with POST method and no Action as native forms and will route them through its hosted form system.

5. Check Free Account/Form Limit

• If you're on a free Webflow plan, there's a form submission limit. If exceeded, forms throw errors.
• Go to Project Settings > Forms to check your current usage and limits.

Summary

Your form is failing because Webflow requires Method: POST to process native form submissions. Change the form method back to POST, remove any custom Action URL if not integrating externally, and Webflow’s backend should handle it as expected.
