I have been trying for days to get my store designer to work and with the error, it creates a template then if save and apply is selected it copies the name stores the template then tells you there is already a template with that name. If you go to the template and just click apply I get the error .I spoke to Ebay and the person I spoke with didn't really know anything about how to revert your store he simply told me you can not revert your store I just signed up with 3dsellers a few days ago and I am running into this problem please fix.
