Question

I don’t know why but when use the follow RewriteRule in my .htaccess file I am getting a Internal Server Error 500. I have mod_rewrite enabled I’ve been looking for a solution all day.

# Enable Rewriting  
RewriteEngine on  
# Rewrite user URLs 
RewriteRule ^(.*)/?$ users\/$1\/index.php

Answer 1

Most likely the 500 error is due to a redirect loop.

You rewrite ANY request to users/$1/index.php including that very URL itself so you end up with a rewrite loop.

Try changing your rewrite rules to this:

RewriteEngine On

RewriteCond %{REQUEST_URI} !^/users
RewriteRule ^(.*)/?$ users/$1/index.php

By checking that the URI doesn’t begin with /users you can avoid the rewrite loop.
