Okay so you need to use the root to verify the domain first. Just stop the redirect to /index.php long enough for you to insert Google's verification code. Then turn back on the redirect. What google is trying to accomplish is to verify you actually do own the new domain. Since some domains share directories this is the only way for them to know you do own the domain since you can verify you control it at root. Hope that helps, Don

Perfect. Thank you
