Support for Drupal 7 is ending on 5 January 2025—it’s time to migrate to Drupal 10! Learn about the many benefits of Drupal 10 and find migration tools in our resource center.I receive the following error in drush when I enable the latest .dev of fast_404 on Drupal 7.
The settings.php is configured as follows:
preg_match(): Unknown modifier 'd' fast_404.inc:70
The error appeard on every cache flush.
# Load the fast_404.inc file. This is needed if you wish to do extension
# checking in settings.php.
require_once('./sites/all/modules/contrib/fast_404/fast_404.inc');
# Disallowed extensions. Any extension in here will not be served by Drupal and
# will get a fast 404.

# Drupal 8 (see: http://drupal.org/node/76824).

# By default we will show a super plain 404, because usually errors like this are shown to browsers who only look at the headers.
# However, some cases (usually when checking paths for Drupal pages) you may want to show a regular 404 error. In this case you can
# specify a URL to another page and it will be read and displayed (it can't be redirected to because we have to give a 30x header to
# do that. This page needs to be in your docroot.
#$conf['fast_404_HTML_error_page'] = './my_page.html';
# By default the custom 404 page is only loaded for path checking. Load it for all 404s with the below option set to TRUE
$conf['fast_404_HTML_error_all_paths'] = FALSE;
# Call the extension checking now. This will skip any logging of 404s.
# Extension checking is safe to do from settings.php. There are many
# examples of this on Drupal.org.
//fast_404_ext_check();
# Path checking. USE AT YOUR OWN RISK (only works with MySQL).
# Path checking at this phase is more dangerous, but faster. Normally
# Fast_404 will check paths during Drupal boostrap via hook_boot. Checking
# paths here is faster, but trickier as the Drupal database connections have
# not yet been made and the module must make a separate DB connection. Under
# most configurations this DB connection will be reused by Drupal so there
# is no waste.
# While this setting finds 404s faster, it adds a bit more load time to
# regular pages, so only use if you are spending too much CPU/Memory/DB on
# 404s and the trade-off is worth it.
# This setting will deliver 404s with less than 2MB of RAM.
//fast_404_path_check();

AnybodyThe fix can be found here https://drupal.org/comment/7916539#comment-7916539 in Comment #10.
Would you be so kind to fix this in the README.txt example and create a new .dev release? I think otherwise other people will run into the same problem.
