I get the following error messages every now and then:
Cannot modify header information - headers already sent by (output started at ... index.php:29) in ... common.inc on line 266.
Cannot modify header information - headers already sent by (output started at ... front_page.module:146) in ... common.inc on line 266.
index.php, line 29:
print theme('page', $return);
front_page.module, line 146:
print theme('page', $output);
common.inc, line 266:
header('Location: '. $url);
I would be grateful for any help!

There is tons of information
There is tons of information on this forum about the header not sent error message. It is mostly a theme or module issue. It shouldn't affect your data.
It will probably go away when you upgrade to Drupal 5.
Theme issue?
Thank you, lhtown. I've gone through those tons of information, but to no avail (no blank lines or white spaces before or after php tags, etc.). The thing is that output starts at index.php, and when starting at front_page.module, it points all the same to
print theme('page'...So you are probably right, it is mostly a theme issue, but everything seems to be ok with theme.inc, template.php, page.tpl.php and so on.
What else could it be?
