Your site displays an unexplained 406 "Not Acceptable" error

If you get a 406 error, the most common reason is that our web firewall (WAF) detected your request as potentially malicious and blocked it to protect your website.

But don't worry, our technical support can modify the web firewall configuration upon your request.

To facilitate processing, please include the following information in your request:

• your public IP address
• URL used
• date and time the error appeared

Our technical support can also simply disable the web firewall for your entire hosting, or for one of your domains, but we generally do not recommend this as it lowers the security level of your hosting.
