[Plugin: Formidable Forms] Formidable ReCaptcha not working in multisite

There’s a new release (1.4.4) that fixes the reCaptcha problem and improves the Akismet integration. For more details on the reCaptcha issues, take a look at this post:

Thank you. I’ll check it out.

I had the same problem in version 1.05.02. I am also on a multisite installation. I got the following error “Captcha Input error: Invalid referer”. The problem was that I mapped the site to an other domainname. Therefore I needed to register the domainname on the recaptcha site (https://www.google.com/recaptcha/admin/list). Then I got a socket error on my page … ?Could not open socket“ … this occurs because I am behind a proxy. The solution is described in the following post:

While I updated formidable the file /export/htdocs/wp-content/plugins/formidable/classes/recaptchalib.php had been overwritten. There was the proxy enabling code.
