The URL of the link is invalid so the link on the page is "http:/?hsLang=en". The footer might be a global module, you can edit the content and links for a global module from the Design Tools: when you view the code for module, there will be a button on the right to "Edit global module". If it's not, it might that the URL for the link is hardcoded into the module, so either way I think you need to check the code.
