 * Hi all,
 * In the WordPress backend i’m creating categories for posts. Like everyone else.
   But if use the dutch words Trouwfilm en trouwfotografie, translated to English:
   Wedding films and wedding photography, i get an error: No naughty business please!.
   Since when is this naughty business? Is this a wordpress thing or a plugin thing
   or a…. This is a problem. Someone has a fix? Or workaround?

 * I couldn’t find this message in any WordPress core file.
 * That said, this is not what you may be thinking: the “naughty business” has nothing
   to do with foul or NSFW language. It’s rather about security!
 * Among geeks and gamers generally, “No naughty business” means no cheating or 
   breaking the rules, and developers often use this to indicate a security check
   has failed. I found a couple of instances (like [here](https://gist.githubusercontent.com/shizhua/3075a9538566f1dbd453/raw/0a9d0c39605d92fc438166bb2452f88eb7df5cb8/like-it-function.php))
   where WordPress developers use the phrase when a **Nonce** verification fails.
 * So, no, it’s not from WordPress itself, and no, it’s not about the use of foul
   language. Rather, _something_ in your setup or _some action_ you’re performing
   is triggering a security check failure from _something_ on your site. What exactly?
   That’ll require digging into logs!

 * The message could also be coming from your hosting provider. If necessary, contact
   their support team.
