URL rewriting using htaccess gives 500 internal server error in subdomains [duplicate]

Question

This question already has answers here:

.htaccess mod_rewrite > 500 Internal Server Error (7 answers)

Closed 6 years ago.

I'm using this code to rewrite in htaccess

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>

<IfModule !mod_rewrite.c>
    ErrorDocument 404 /index.php
</IfModule> 

It works fine in example.com/sub , but in sub.example.com it gives 500 internal server error (except for the landing page).

I can't understand what wrong here. Sometimes it may be very simple. I'm using GoDaddy.

Answer 1

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>

This works for me.

Answer 2

You can try this code:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^((?!index\.php).*)$ index.php?/$1 [L]
</IfModule>

<IfModule !mod_rewrite.c>
    ErrorDocument 404 /index.php
</IfModule> 

Answer 3

Try this:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /

    RewriteCond %{REQUEST_URI} ^system.*
    RewriteRule ^(.*)$ /index.php?/$1 [L]

    RewriteCond %{REQUEST_URI} ^application.*
    RewriteRule ^(.*)$ /index.php?/$1 [L]

    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>
<IfModule !mod_rewrite.c>
    ErrorDocument 404 /index.php
</IfModule>

assumming that index.php is your index page.

and change in config.php

$config['index_page'] = '';

Answer 4

I had the same problem, even with .htaccess written properly. Took me a moment to realize the file permissions were wrong. Doh!!!

IMPORTANT: PHP files must not have 777 permissions. If you are trying to open a PHP file that has such permissions, it will result in an "Internal Server Error 500". To resolve the problem, simply change the permissions of the file to 644 or 755.
