FAQ 2.1

[edit] The error message "Warning: Cannot add header information - headers already sent by ..." is displayed, what's the problem?

Edit your config.inc.php file and ensure there is nothing (I.E. no blank lines, no spaces, no characters...) neither before the <?php tag at the beginning, nor after the ?> tag at the end. We also got a report from a user under IIS, who used a zipped distribution kit. The file libraries/Config.class.php contained an end-of-line character (hex 0A) at the end; removing this character cleared his errors.

Note that this output can sometimes be cleared and normal output restored by hitting refresh, however this seems to be browser-specific.
