we recently launched a new website and in doing so have lost access to the old admin site. Both sites are using Magento 1 and we used to access the old site on the following URL, https://www.alltank.co.uk/index.php/manage
Now that takes you to a 404 on the new site and I don't know how to get back to the new one?
New site is on AWS
Old site is on Freethought
