 * My website: [http://tinyurl.com/lg4kjsg](http://tinyurl.com/lg4kjsg)
 * I enabled falcon engine for my website and got Error 500 – Internal Server Error.
   I copied my old .htaccess file and now my website is online.
 * What could cause this problem ? How can I use falcon engine feature?

 * **Same problem for me – further info**
 * Thank you for your work on Wordfence, including Falcon.
 * The site was on WordPress 3.8.x with WordPress 5.0.2; Falcon was working fine.
   
   Upgraded WordPress to 3.9, and Wordfence from 5.0.2 to 5.0.3; the site worked
   fine (the upgrade disabled Falcon).
 * When I enabled Falcon, I got “Internal Server Error”; restoring .htaccess brought
   the site back OK.
    The error log shows: /var/www/html/wordpress/.htaccess: order
   not allowed here
 * Re-enabling Falcon and commenting out line 2 of .htaccess: “Order Deny,Allow”,
   the site seems OK,
    although it may not be secure or working totally correctly
   without that line.
 * Now running on Basic Caching until this is fully resolved.

 * Hi,
 * This is because your site admin has disallowed you to use IP blocking in .htaccess.
   It’s something specific to your config, not a bug in Wordfence. Read this for
   more:

 * Also google around for the specific error you’re getting, it’s a common problem.
 * I got your email re the beta, and we’re not going to add a fix for this because
   it’s an issue with your config and not Falcon.
 * Regards,
 * Mark.

 * I checked my virtual host configuration and it seems already have correct configuration.
 *     ```
       <Directory /var/www/virtual/mywebsite.com/htdocs>
            Options -Indexes Includes FollowSymLinks MultiViews
            AllowOverride All
            Order allow,deny
            Allow from all
       </Directory>
       ```

 * [@mmaunder](https://wordpress.org/support/users/mmaunder/),
 * After I read your answer, I thought this problem is related to user on my web
   server.
 * I changed my website’s owner permissions from “user:www-data” to “www-data:www-
   data”
 * And now, It worked for me.
 *     ```
       cd /var/www/mywebsite.com/
       find -exec chown -R www-data:www-data {} \; -print
       find -type d -exec chmod 755 {} \; -print
       find -type f -exec chmod 644 {} \; -print
       chmod 600 wp-config.php
       chmod 604 .htaccess
       ```

 * Hi Mark,
 * Pecking around trying to find out what exactly “Falcon” is?
 * This one makes me a little nervous since it writes to htaccess –
 * Can we enable / disable it? What does it do? Or where can I read about it?
 * Thanks!
