My theme that I chose in "Manage My Store" has always been a red theme that matches my logo.
Here are the old style links to my store which no longer work:
http://stores.shop.ebay.com/AstoundingTreasures
https://pages.ebay.com/AstoundingTreasures
Ebay even shows this link as the link to my store in "Manage My Store" but neither one of these links works anymore.
The NEW format link to my store is this one:
https://www.ebay.com/str/astoundingtreasures
The theme now is just some generic blue and white theme that I can't change.
