Why is my Google home page suddenly coming up in French? I go into the settings, but I can't seem to fix the problem.

Try deleting all temporary internet files and cookies.

If that doesn't work add a "/ncr" the back of Google. This will keep it from redirecting to another location.
Ex..
http://www.google.com/ncr
http://www.google.co.za/ncr
http://www.google.com.au/ncr

Hope this helps...

Cheers
