Groups - Deleting Discussions

[GMMichael]

Trying to do some housekeeping on my community/group, and when I try to delete a discussion I get this:

PHP Warning: require(..../dbtech/userthreads_pro/hooks/group_start_postcheck.php): failed to open stream: No such file or directory in ..../group_inlinemod.php(108) : eval()'d code on line 1

Fatal error: require(): Failed opening required '/var/www/virtual/enworld/forum/dbtech/userthreads_pro/hooks/group_start_postcheck.php' (include_path='.:/usr/local/lib/php') in /var/www/virtual/enworld/forum/group_inlinemod.php(108) : eval()'d code on line 1

I went into another discussion and deleted the initial post, and now the discussion still shows up in the discussions list with the note "Discussion deleted..." Is this visible only to me (group leader)?
