I get an error after clicking submit on the registration page:
Could not open socket
Haven't really changed anything. what could be the reason ? and solution ? :S
This happens when the reCAPTCHA plugin fails to connect to the reCAPTCHA server. Your server may not support opening a connection to remote hosts.
Either find out why the connection is failing or use a different CAPTCHA module (spambot countermeasures in the admin control panel).
