My site displays an unexplained 406 "Not Acceptable" error

If you get a 406 error, the most common reason is that our web application firewall (WAF) detected your request as potentially malicious and blocked it to protect your site.
But don't worry, our technical support can adjust the web application firewall configuration on simple request.
To speed up handling, please include the following information in your request:
- your public IP address
- URL used
- date and time the error appeared
Our technical support team can also simply disable the web application firewall for your entire hosting account, or for one of your domains, but we generally don't recommend this as it lowers your hosting's security level.
