.htaccess file causes "500 Internal Server Error" but no error log entry

Question

I set up an apache manually and added a second web directory with this code:

Alias /webs c:\webs
<Directory /webs>
    AllowOverride All
</Directory> 

However, this web has an .htaccess file in it and accessing the website gives the error: "500 Internal Server Error", but does not write anything in the error log file.

But when I remove the .htaccess file, I don't get this error.

I added the "AllowOverride All" line and restarted the server but this doesn't correct the error.

My .htaccess is this:

RewriteEngine On
RewriteCond %{REQUEST_URI} !(\.css|\.js|\.png|\.jpg|\.gif|robots\.txt)$ [NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?params=$1 [L,QSA]

<Files "test">
    Order Allow,Deny
    Allow from all
</Files>

What do I have to do so that I can use an .htaccess file in this directory?

Solution

Enable mod_rewrite in Apache web server. Also try this:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{REQUEST_URI} !(\.css|\.js|\.png|\.jpg|\.gif|robots\.txt)$ [NC]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php?params=$1 [L,QSA]

    <Files "test">
        Order Allow,Deny
        Allow from all
    </Files>
</IfModule>

If mod_rewrite is enabled then initiates the rewrite engine; else it does nothing.
