You have to set your headers before you send any output to the browser.

So if you have <HTML> and then <?PHP // send header info ?>, the script will crash. All headers must precede any displayed content.

PHP doesn't really like you setting cookies or sessions outside of the header, and if you look at your error it has to do with your sessions. This info must be put before your first <html> tag.

It seems as if the new PHP 4.3 is not very forgiving about this whereas 4.23 seemed to be more flexible with it.

Hope this helps!

Hmm ok I think I understand. So I went through my sessions.ph file and didnt find anything about <HTML>.

So How does someone fix this?
Like is there a tutorial?

Can't really troubleshoot without code, post some...

If any character is sent before the headers PHP automatically sends the html headers and then sends the character.
Any php script that does not have <? as the first characters will have already sent the headers and a character.
Even a blank line or space before the <?php tag causes this to happen.

Good luck
