fancy URL problem - startpage without name but extention

[Belletage]

Hi, super!
thank you very much!! the lonesome extention is gone :-)

for the wrong placed 'index'-name, I remove %parent% from the permalink.

another small kink:
when I change the browsers language (Mozilla SM), the corresponding language-sites are shown, with an inserting of the 'nondefaultlanguage' as "folder" like 'en':
domainname.de/en/about.html
but when I switch the browser back, the 'nondefaultlanguage'-"folder" doesn't vanish
and the language stays fix.

best, Bell.
