I have a Wordpress installation in a domain and within a directory, I have a site developed in PHP+MySQL completely independent of the wordpress. It works alone. This site is a backoffice, so it's installed under the /backoffice/ directory.
One of the directories of the backoffice I have another directory I want it works with friendly URL's.
In my .htaccess I have the following rules:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^backoffice/edit_user/([^/\.]+)/?$ /backoffice/edit_user/index.php?o=$1 [L,NC,QSA]
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_URI} !=/server-status
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
RewriteRule ^login/?$ wp-login.php [QSA,L]
RewriteRule ^postpass/?$ wp-login.php?action=postpass [QSA,L]
RewriteRule ^logout/?$ wp-login.php?action=logout [QSA,L]
RewriteRule ^lostpassword/?$ wp-login.php?action=lostpassword [QSA,L]
RewriteRule ^retrievepassword/?$ wp-login.php?action=retrievepassword [QSA,L]
RewriteRule ^resetpass/?$ wp-login.php?action=resetpass [QSA,L]
RewriteRule ^rp/?$ wp-login.php?action=rp [QSA,L]
RewriteRule ^register/?$ wp-login.php?action=register [QSA,L]
When invoked a url like this one: mydomain.com/backoffice/edit_user/joseantonio the 404 page come up.
What's wrong?
Thanks in advance.
