RewriteEngine i Error stranice

[mbozick1]

Pozdrav!
Naime, konfigurirao sam .htaccess file na sljedeci nacin:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ $1.php [L,QSA]
ErrorDocument 404 /errors/404.php
ErrorDocument 500 /errors/500.php

kako bih se rijesio php ekstenzije u URL-u i kako bi definirao custom error page u slucaju odlaska na adresu koja ne postoji na serveru.
Medjutim, kada upisem neku krivu adresu ne izbacuje mi moje customizirane error stranice nego mi izbacuje standardnu Internal server error:

Internal Server Error
 The server encountered an internal error or misconfiguration and was unable to complete your request.
 Please contact the server administrator and inform them of the time the error occurred, and anything you might have done that may have caused the error.
 More information about this error may be available in the server error log.
 Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

Ima li netko ideju kako da napravim da mi rade te kustomizirane stranice za greske sa rewrite-om?

Problem je riješen sljedećim kodom u .htaccess file-u:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^(.*)$ $1.php [L,QSA]
ErrorDocument 404 /404.php
ErrorDocument 500 /404.php
