URL Rewriting on Apache server causes 404 error page - apache

Question

A few weeks ago I was trying url rewriting on my shared host. It was working for a while, but nowadays it seems to be broke. I don't know what the problem is and I can't solve it by myself. Hope you could help, guys.
This is the plan. I want to delete the extension in the url (e.g. 'file.html' or 'file.php') to only the filename (e.g. 'file'). My code is the following:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule ^index/(.*)/$ index.php?page=$1
RewriteRule ^([^\.]+)$ $1.php [NC,L]
RewriteRule ^([^\.]+)$ $1.html [NC,L]
ErrorDocument 404 404.php
ErrorDocument 403 403.php
ErrorDocument 401 401.php
</IfModule>
One extended note: this .htcaccess file is in the directory 'portfolio'. The root has another .htcaccess file which is the following:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . index.php [L]
</IfModule>
Maybe it is something obvious, but I couldn't find what the problem is. I did try 'RewriteBase /website/', 'RewriteBase /', 'RewriteCond %{REQUEST_FILENAME} !-f' and 'RewriteCond %{REQUEST_FILENAME} !-d' in the first .htaccess file, but that doesn't work.

Answer 1

You can have these rules in /portfolio/.htaccess
ErrorDocument 404 404.php
ErrorDocument 403 403.php
ErrorDocument 401 401.php
RewriteEngine On
RewriteBase /portfolio/
RewriteRule ^index/(.+?)/$ index.php?page=$1 [L,QSA]
RewriteCond %{DOCUMENT_ROOT}/portfolio/$1\.html -f [NC]
RewriteRule ^([^.]+)$ $1.html [L]
RewriteRule ^([^.]+)$ $1.php [L]
Your rules for adding .php or .html need to have a RewriteCond to check whether corresponding files exist in your portfolio directory.
