Can I create a new site with the same free Wix URL as an old site?
You cannot publish two free Wix sites with the same URL. If you would like to create a new site with a free Wix URL that you have already used for an old site, you will first need to delete the old site.
To delete a site: Sign in to your Wix account > next to the relevant site, click Manage Site.
Under Website Actions, click Show More > click Delete Site.
Note: Deleting a site does not cancel any premium plans attached to it, nor does it cancel your Wix account.
