Hi,

The cause of these issues is that the hosting provision you have is using frames to host your website domain. I'm not sure how this could have changed recently as it's part of the service provided by 1and1 but you'd need to work with them to resolve this.

Our suggestion is that you use regular DNS based hosting for your domain which would properly redirect users to our servers and everything will return to working as you'd expect.

Thanks,

Rob Denison.
