Error "Access denied with code 406" OR Error "Not Acceptable An appropriate representation of the requested resource / could not be found on this server" (mod_security)

If you are seeing in your browser or in your site access log the following two error logs:


"Access denied with code 406" 

OR

"Not Acceptable An appropriate representation of the requested resource / could not be found on this server"

That means that your application/site has triggered one of our default application firewall rules (for our shared Linux, and shared Linux reseller servers - modsec / mod_security). Please, contact our support so that we can assist you with this error.
