Description (last modified by Ryan J Ollos)

Seeing the following error with reCAPTCHA2:

2016-03-02 19:39:42,444 Trac[recaptcha2] WARNING: reCAPTCHA returned error:   "success": true,

The problem is that the reCAPTCHA2 API returns JSON, but the response is handled as if it was a newline delimited string: plugins/1.0/spam-filter/tracspamfilter/captcha/recaptcha2.py@14567:82#L63 .

The reCAPTCHA API returns string data, so the issue here may be that the code was copied from tracspamfilter.captcha.recaptcha.

Another issue I noticed while working in a dev environment is that the reCAPTCHA2 image is not rendered because the Submit button is placed inside the div where the captcha is rendered. The JavaScript that adds the image expects the div to be empty.

Patch forthcoming.

Fixed in [14578], but I'll leave the ticket open until the fix is confirmed on the production server.
