Upload the attached file to your admincp folder
Then go to:
http://YOUR-SITE-URL/admincp/move_de...s.php?forumid=X
Replace "
X" with the Forum ID you want to move the soft deleted threads to, once the the page is loaded, you should get a message saying "done"
Now go to:
http://YOUR-SITE-URL/admincp/misc.php?do=chooser
and rebuild your thread and forum information
Give it a minute or two to process and you're done!
