 * Hi,
 * Im experiencing an issue when posting a topic/reply in which the page then tries
   to send the email notification. After submitting you are taken to an error page
   with the error code ‘Fatal error: Call to undefined function mb_convert_encoding()
   in /wp-content/plugins/bbpress-notify-nospam/bbpress-notify-nospam.php on line
   1000
 * Tried a couple things but struggling to resolve! any advice?
 * Thanks!

 * Hi [@leapness](https://wordpress.org/support/users/leapness/),
 * Where are you hosting your site? `mv_convert_encoding()` should be available 
   in your host’s PHP (what version is it, btw?).
 * Anyway, I found a replacement for `mb_convert_encoding()` and will be applying
   it later today.
 * Thanks for the heads up.
 * Cheers,
    Vinny

 * Aha! Found the issue to be the hosts PHP config! upped the PHP version to 7+ 
   which has mbstring enabled unlike 5.6..

 * Good to know. I’ll release the fix nevertheless for those who don’t have it available.
