Localizations Brazilian Portuguese (thanks to Vinícius Ferraz) Spanish (thanks to Ivan Yivoff) Italian (thanks to Salaros) German Latest Files on GitHub: https://github.com/tareq1988/wp-recaptcha-integration Compatibility On a WP Multisite you can either activate the plugin network wide or on a single site. Activated on a single site everything works as usual. With network activation entering the API key and setting up where a captcha is required is up to the network admin. A blog admin can override the API key e.g. when his blog is running under his/her own domain name. Known Limitations You can’t have more than one old style reCaptcha on a page. This is a limitiation of reCaptcha itself. If that’s an issue for you, you should use the no Captcha Form. A No Captcha definitely requires client side JavaScript enabled. That’s how it does its sophisticated bot detection magic. There is no fallback. If your visitor does not have JS enabled the captcha test will not let him through. On a Contact Form 7 when the reCaptcha is disabled (e.g. for logged in users) the field label will be still visible. This is due to CF7 Shortcode architecture, and can’t be fixed. To handle this there is a filter recaptcha_disabled_html. You can return a message for your logged-in users here. Check out the GitHub Repo for details. As of version 4.3 CF7 comes with its own recaptcha. Both are supposed to work together. I you want to keep the WP ReCaptcha functionality, e.g. if you want to hide the captcha from known users, leave the integration in the CF7 settings unconfigured. Old style reCaptcha does not work together with WooCommerce. In WooCommerce the reset password form can not be protected by a captcha. Woocommerce does not fire any action in the lost password form, so there is no way for the plugin to hook in. Take a look at this thread for a workaround. Due to a lack of filters there is no (and as far as one can see, there will never be) support for the MailPoet subscription form. Plugin API The plugin offers some filters to allow themes and other plugins to hook in. See GitHub-Repo for details.
