To turn off optimization:
Redirect Service: If you have a redirect service in place, you can simply redirect traffic for you domain to your No Optimization Code. Make sure to properly insert your domain name into the redirect string. For example:
http://landing.domainsponsor.com/?a_id=<A_ID>
In the above url, substitute your DS user id for <A_ID >
All of this is explained on the Get Code page from the main menu once you have logged onto DS.
If that does not help, then contact DS tech support. PM me if you need a contact & phone no.
