Hi, it looks like e you haven’t created a sub directory for french? As the link to french should be
http://www.maxlingua.net/french/fran%E7ais.html or which ever name you gave the new folder/directory. I noticed that your link is only part of the url
http://www.maxlingua.net/fran%E7ais.html
If you are getting more involved with languages you actually might of be better off creating sub domains for each one, as it looks like a site that may grow. I was under the impression that there were just a few pages. But not to worry you can still do it this way.
1st thing to do is delete this page
http://www.maxlingua.net/index.html this is not the correct way to have an index page.
2nd Have you created a folder in your c panel called “french” ?
3rd if you have done the above, create a duplicate of your English index page & save it in a folder called french on your home computer. Now re-open this file called index & change the text on this page from English to French. Now you save & publish this file to public_html/french/ to have a link to this page from a Spanish or English page it would look like
http://www.maxlingua.net/french/
4th If you then added another page to the French directory called services. You would publish to public_html/french/ & the link to this page would be
http://www.maxlingua.net/french/sevices.html
See how you get on from here.
