UBB.Developers Forums UBB.threads 7 Development How Do I? "Cannot Modify Header Info" Error on Who's Online (6.4)

I'd check the online script, template and language file and make sure there's no extra spaces after the php closing tags. [/]

So what do you suggest if one can't find any offending white space?

My particular problem is that I have login box on my site's index.php. It all worked fine when I was running 6.2 but when I recently upgraded to 6.4, I start getting these errors (headers already sent, etc).

And, I only get the error the first time I hit the site and I'm already logged in. If I go to the forums and return to the main site index, I won't see the error again.

My login box is simply a hacked loginpal script, with a lot of stuff trimmed out, and the user authetication added at the beginning. The error I get is:

Warning: Cannot modify header information - headers already sent by (output started at /usr/www/users/vfighter/index.php:24) in /usr/www/users/vfighter/versuscity/ubbt.inc.php on line 572

and line 572 of ubbt.inc.php is the call to setcookie.
