.htaccess URL Redirecting giving 500 Internal Server Error

Question

I have a .htaccess file that is working fine on Apache server on Windows 7, but giving 500 Internal Server Error on LightSpeed Server. This is my .htaccess file:

<Files ~ "^\.(htaccess|htpasswd)$">
deny from all
</Files>
AuthUserFile **********************
AuthGroupFile /dev/nullAuthName "Please enter your ID and password"
AuthType Basic
require valid-user
order deny,allow

Options +FollowSymLinks
RewriteEngine on
RewriteBase /someFolder
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^(.*)$ $1.php
RewriteRule /R/(.*)/ index.php?R=$1

Answer 1

Options +FollowSymlinks will cause a 500 error if the server hasn't set AllowOverride Options=FollowSymlinks.
