Doesn't work for me, unfortunately. The Who's Online screen dissapears and everything seems to work flawless. But as soon as I send a private message to a User and the User deletes this message (after viewing it), the User gets the following error message:
Warning: Cannot add header information - headers already sent by (output started at d:\www.domain.com\htdocs\xxx\ubbt.inc.php:1690) in d:\www.domain.com\htdocs\xxx\delete.php on line 78
If the User clicks the Brower's BACK button, the message is deleted and everything works flawless as before. Any hints what the problem might be ???
