404 error

[yojoe]

Your server doesn't seem to support .htaccess
If you disable fancy URLs it will work. (I opened some pages of your site by changing in the URL '/contact' to '/index.php?id=contact')

It may not be server's fault, but wrong mod rewrite's directive
Look at the url: http://filmpl.toile-libre.org/getsimple/
filmpl has moved his site to a new location (directory or a subdomain), thus directive

Code:

RewriteBase /getsimple

leads to 404.

changing it to

Code:

RewriteBase /

or even deleting whole line should do the job.

with friendly urls turned off, links doesn't point to domain/getsimple
