@[deleted]In order to change this setting you must edit the `include/class.topic.php` file. In this file search for "Topic is too short." and you will find these two lines:
388 elseif (strlen($vars)<5)
399 $errors=__('Topic is too short. Five characters minimum');
Change these two lines to accomplish what you're looking for. For example, if you want it to be 3 character minimum then change the lines to:388 elseif (strlen($vars)<3)399 $errors=__('Topic is too short. Three characters minimum');I hope this helps! Cheers.
