htaccess line - 500 error

I have a htaccess fil开发者_JS百科e:

<IfModule mod_rewrite.c>
RewriteEngine On

RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

I want to add the line below, but it gives me 500 error.

Options -Indexes

Can somebody help?

Check if the directory where your .htaccess lives in has enabled the neccessary AllowOverride (enabled must be: AuthConfig and Options at least) in the httpd.conf.

Make sure it is not within the

<IfModule mod_rewrite.c>
...
</IfModule>

part of your .htaccess

Usually you should have a logging-message in your error-log. I assume, that you will find something like this:

[alert] [client 192.xxx.xxx.xxx] /path/to/web/.htaccess: Options not allowed here

This solution does not always help (depending on the apache-version you are using): In some cases you have to move this section to your httpd.conf to make it work.

It is explained in detail in the apache-docs.
