Hairy .htaccess Dreamhost WordPress Problem Solved! [en]

[fr] Résolution d'un problème qui m'a littéralement empoisonné mes vacances. Ouf.

Thanks to grimboy, my “parent” .htaccess now has two extra lines and looks like this (and the problem that has kept me awake for the last week is solved):

AddDefaultCharset OFF
# BEGIN WordPress

RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} ^/membres.*$ [OR]
RewriteCond %{REQUEST_URI} ^/failed_auth.html$
RewriteRule ^.*$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php

# END WordPress

Thanks so much!
