never mind i already figured out and make it works for ver 3.06 this very cool
onlything you have to do is add too queries into your sql database.
ALTER TABLE `forum` ADD `thanksmessage` text NOT NULL;
ALTER TABLE `forum` ADD `thanksenabled` int(1) UNSIGNED DEFAULT "0" NOT NULL;
--------------------------------------------------------------------------------
log on to your
http://ww.yourdomain/AdminCP
go to Import & Maintenance/Execute SQL Query
import each queries at a time.
after installed then it should work.
ps:/ if you want to make all forums thread enabled automaticly so you do'nt have to turn it on for each one. just change :
UNSIGNED DEFAULT "0" NOT NULL; "TO" UNSIGNED DEFAULT "1" NOT NULL;
as a part above .. but not recommended until you allow all threads..
good luck,
any question let me known.
