Warning: cannot add header... error on site, any ideas?

[Ember]

Ok, I am developing a new gaming site, and it was coming along nicely until I added a welcome bar to the front page, and that worked fine last night, but now it gives this error:


Warning: Cannot add header information - headers already sent by (output started at /home/httpd/vhosts/******/httpdocs/v1/functions/func.php:45) in /home/httpd/vhosts/******/httpdocs/forums/admin/functions.php on line 1599


I ***'d out the host cos the site is still in early development and we're yet to register the domain name we want, no risks ;)

Anyways, any ideas?

Yah, I read that now and editing some stuff... however...

The error shows on my site the first time... and then when I enter the forums, and go back to the site and hit refresh, the errors gone... its really confusing.
