- or any new Admin UI interface
You need to change core files, so you will need to repeat this after update.
Open forum_admin.php file
look for something like
$batchCopy (line cca 119)
it could be commented or set to false
just set it true or delete comment
protected $batchCopy = true;
As result you will have option to copy your forums in admin area.
Why it is important for me? My subforums are similar, I want to copy them and just rename title and SEF-URL. No need to set visibility, rights, parents etc.
