Apache2, which is installed on our servers, is strict about syntax errors, especially rewrite rules defined in your .htaccess files.

If your home page or any other page displays an error, rename the .htaccess file. Alternatively, comment out every line with # and then uncomment them line by line until you arrive at the part that is causing the problem.
Here is an example of a rewrite rule that was accepted in Apache 1.x but which is no longer valid in 2.x:

RewriteRule ^fr/appartement/([a-zA-Z0-9]+)\Pieces.htm$
./fr/appartement/$1Pieces.php [L]

The \P is not valid.


In addition, when moving to Apache2, some modules are no longer supported on our servers:
mod_auth_anon, mod_auth_dbm, mod_authz_dbm, mod_cern_meta, mod_imap, mod_imagemap, mod_mime_magic
