If you have trouble managing your website (on Vistaprint) using Internet Explorer, as can happen, then fire up Google Chrome and search using Google for “Dashboard Vistaprint”. When the page appears click on 'My Account' at the top then look for 'My Resources' and choose Websites, then Edit Website (at the top) or Website Dashboard (on the left hand panel, where you can also choose to create your Mobile webpage or edit your Blog - as I am doing now!).
Voila! I hope this works in the future
