In this article we'll discuss disabling mod_security on your account via our Modsec Manager plugin for cPanel.

If you don't know what mod_security is, you might want to first check out our article on what is mod_security and why is it important.

Also you might be getting 406 Non Acceptable Error Messages from having mod_security enabled as well.

Below are the steps to follow to disable mod_security for one of your domains.

Note! You may not have the option to enable or disable mod_security in your cPanel on VPS or Dedicated servers. To disable mod_security on accounts that don't have the option in cPanel, you will need to use command line via SSH or contact tech support to disable/enable it for you.

  1. Login to cPanel
  2. modsec-managerUnder the Security section, click on Modsec Manager.
  3. modsec-manager-default-onmod_security will be on by default for all your sites, shown by a checkmark beside them.
  4. modsec-manager-update-offRemove the checkmark beside the domain you wish to turn mod_security off for, and click Update.
  5. modsec-manager-completeYou should now see that mod_security was disabled for the domain you selected.
  6. modsec-manager-disabledIf you have mod_security disabled, you'll see a blank checkbox beside the domain.
  7. modsec-manager-update-onTo enable mod_security on a disabled domain, place a checkmark beside the domain and click on Update.
  8. modsec-manager-enabledYou should now see that mod_security was enabled for the selected domain.

You should now know how to turn mod_security on and off for any of your domains that might be encountering problems relating to it being enabled by default.

This error is indeed typically caused by mod_security. We recommend using the Modsec Manager described in this article to turn mod_security off.

I followed the instructions but I am still recieving the an error message on my site. The error message Looks like:

"Error 406 - Not Acceptable

Generally a 406 error is caused because a request has been blocked by Mod Security. If you believe that your request has been blocked by mistake please contact the web site owner."

Hello Janice,

If you are still getting the error, you will want to contact our Live Support team to have them take a look for the specific rule that is being violated.

Kindest Regards,
Scott M
