function clean($raw) {
// Replace spaces with dashes] & convert to lower case
$raw = strtolower(str_replace(" ", "-", $raw));
return preg_replace("/[^a-z-]/", "", $raw);
}

Change last line to
return preg_replace("/[^a-z0-9-]/","",$raw);
to fix.

Priority: Critical » Major
  • Critical is used to designate broken functionality that makes the project unusable. "Critical" should be reserved for the most problematic and important issues. Abuse of the Critical field will likely get your issue ignored by a developer.
  • Major is used for issues which have significant repercussions, but do not render the whole system unusable.
