Front-end article editor submissions fails with reCaptcha v2

reCaptcha v2 is not working for front-end article edit submission. When the save button is pressed the error response is "Invalid field: Captcha" and it returns to the same editor page (with the edits).


Here's the site configuration:



If I instead set mode to code (internal), the above editor submission works correctly.

Any idea what's up with reCaptcha please?

Same problem in groups when sending a private message.

Seams to work fine in my tests. It's possible you've a JavaScript conflict causing the reCaptcha to break. Press F12 to open your browser developer tools while looking at the create article page. Next click the Console tab and now refresh the page. See if there are any errors (they'll be colored red) in the Console tab. The internal modes have backup static HTML logic to avoid this, but there's nothing I can do for external captchas like reCaptcha when there's a JS error.
