# Captcha/ReCaptcha validators. We override the standard validators from
|
|
# plone.formwidget.captcha and plone.formwidget.recaptcha, in order to
|
|
# switch between the two. This is necessary, because the zcml registration
|
|
# of the CaptchaValidator has to be there, no matter which captcha solution
|
|
# is installed, or even when no captcha solution is installed.
