Hello, been trying to install the php version 5.15 and seems to have installed OK, and I have set up an admin account but whenI login I get the following error:
Warning: Cannot add header information - headers already sent by (output started at /home/virtual/fatdog/home/httpd/html/bb/theme.inc.php:97) in /home/virtual/fatdog/home/httpd/html/bb/main.inc.php on line 739
What do I need to do to fix this?
Regards
Dan

Have you made any substantial changes to the theme.inc.php file? For some reason the error is stating that theme.inc.php is printing out some headers.

No, I haven't made any changes to that file. Should I have made any changes to this file.

No, I'm not on vservers, I've actually recently got my own dedicated server to cope with the traffic.
I run redhat linux and apache.
What is AFAIK?

No changes are necessary for the program to work. I'm just not sure what would be causing the problem. The error is basically this. Any cookies that need to be set have to be sent to the browser before anything else. But apparently part/all of w3ttheme.pm is being sent to the browser when it shouldn't be. Are you using the standard php tags? <? and ?>

THanks for the explanation. That's what I thought it meant. I am using standard php tags. Is there anything I should be looking for? Could not setting any of the config-inc settings correctly cause this as there were really the only things I changed.
Regards
Dan

There's one thing you can try. When you get that error, take a look at the source of the HTML page. We might be able to find out what is being printed to the browser by doing this.

Below is the source of the html page. I didn't bother pating all the html that followed.

Well, nothing is getting printed to the browser that shouldn't be, so I'm not sure where the other header is being sent from. It is saying it is coming from theme.inc.php line 97, which is the end of that file.
What version of PHP are you running? Can you email me your theme.inc.php and config.inc.php files so I can take a look at them?

OK, I have sent those files to your email account.
I'm running php 4.04.

Ok, I'm still getting used to what is acceptable in PHP, so here is a guess. Both files you sent look fine, but there is one difference between your theme.inc.php and the default one. You have a couple of blank lines after your closing php tag, the ?> at the end of the file. It's possible that these blank lines are being interpreted as header information.[]/w3timages/icons/crazy.gif[/].
Like I said, I'm not sure, but everything else looks totally normal. So, you can try removing the blank lines after the closing php tag and see if that helps.

Any whitespace at the beginning or end of an included file will cause that error. If the whitespace is enclosed in the tags it's ok. This is a common problem. Most people inadvertanty will hit return key at the beginning or end of a file to cause this. Thank you, Bob [b]Extreme VB Forums -[/b] Visual Basic Help

Thanks guys that solved the problem.
Maybe if this is a common problem then the guys who write php could fix that for in the next release.
Once again thanks

Its a common PHP problem when working with header information. Absolutely nothing can be sent to the browser before the header tag if you want headers to work without error. That includes simple, albiet invisible, line feeds or breaks. --------- Shalazar www.charisma-carpenter.com

Scream,
They are not being intepretated as header information, but header information can not be sent after any information at all, as I guess you already know, and since he's printing blank spaces to the browser before the header, this is enterprated as html..
