What to do when you see this message
The error page most likely shows a CAPTCHA (a squiggly word with a box below it). To continue using Google, type the squiggly word into the box. It's how we know you're a human, not a robot. After you type the CAPTCHA correctly, the message will go away and you can use Google again.
