Known issues

If you've enabled "Fast 404 pages" functionality in your "settings.php" file,
search engines most likely won't be able to retrieve your text key file to verify site ownership.

To avoid this problem, consider removing the "txt" extension from $settings['404_fast_paths']
variable in your "settings.php" file.
