Thank you Whiteg and Keith for your quick answers :)

I had tried before to change 'Allow from .inria.fr' to 'Allow from All' 
and the same thing happened.

And here are the permissions of the directory database:
drwxrwxrwx 2 root root  4096 sep 10 10:29 database/
Is this normal...? The plugin/ directory has the same permissions...

What is stranger is that in database/ I have these different permissions:

-rw-r--r-- 1 root root 1286 aoû  1 15:18 BlaBla
-rw-rw-rw- 1 root root  654 oct  3 13:57 HomePage
-rw-r--r-- 1 root root 2313 sep  5 16:52 BlaBlo
-rw-r--r-- 1 root root  424 sep 10 10:44 BlaBli
(....)

So when I edit and save HomePage, I get a different error message. Here 
it is:

------

Still, HomePage is successfuly saved. (While the other pages can't be 
saved at all.)


Actually I didn't have any problem saving a page when launching the 
standalone server with command 'kwiki -start 8080'. So I wonder wether 
it's a problem with my server configuration or if it's a real bug.
