In short, I replaced my httpdocs (FTP FileZilla) with an earlier backed-up version. Now my Home Page views but nothing else. When clicking on a link I receive an error message stating:
The requested document was not found on this server.
The strange thing is though that the Home Page does not correspond to the home page that belongs to the backed-up version.
Does anybody have an idea what I can do to get the backed-up version working again? Thank you in advance!
