I'm using coolpages.com as my server and when i try to put phpBB on my site, it works fine untill i get done installing. when it installs it comes up with warnings. i read the faq and it said something about security issues. i would really like some help with this issue. Thanks.
It looks like sessions.php and page_header.php are each trying to send header information with the header() function but failing because something on line 19 of config.php is outputting spaces or newlines.
Whenever you try to send header information, you must ensure that no previous function calls or scripts have sent anything, even whitespace. Make sure that there are no echo or other print statements in config.php and make sure there are no spaces or newlines on either side of the <?php ?> tags.
// beginning of config.php
$somevariable = 1;
// other stuff here
// end of config.php
This will cause the errors you're getting, because there are spaces and newlines in the script that the server will interprete and output. The following is okay:
