smileyhappy: Hello
I helped another member update their store a few weeks ago and from memory this is where I went to do it.
From memory I clicked on the words manage my store then I scrolled down the page to where it says store tune-up in the middle of the page and clicked on these words on the link below.
Stores Design Centre:
I hope this helps you if not someone with more knowledge will be able to help you.
Kind Regards
Monty
