UBB.Developers Forums UBB.threads 6 V6 Modifications Archived Mods [UBBT 6.0] Simple Page Protection

Hi Dave,
this is a hack I had trouble to install.
(Maybe it is because I use THREADS 6.01)

If I put the hack as instructed, the following else statement refers to the hack and unregistered users see no content any more, appart from the registered and the unregisterd nav bar at the same time.

If I move the hack BEFORE the last closing } of the regular code it works. But then I get this, If I am not logged in:

Warning: Cannot add header information - headers already sent by (output started at /homepages/21/d24400447/htdocs/php/forum/templates/default/ubbt_header.tmpl:23) in /homepages/21/d24400447/htdocs/php/forum/ubbt.inc.php on line 485

(Line 485 is the line with the setcookie command).

Any idea what might have gone wrong?

Thanks + Greetings
