My original website was in X5 V9 on my old laptop. I have just completely redesigned the website using X5 V11 on a different laptop. For some reason after uploading the redesigned website I now have a header and menu from the old site and images and text from the new. I can't check any other pages as the menu on left side is showing has only two items. The new website sould have the menu along the top.

Help please!
