3.9.20. Warning: Cannot add header information...in forums

You get errors of the form:

Warning: Cannot modify header information  headers already sent

when vieweing the forums. There are two solutions (see Warning: Cannot add header information...in forums):

Near the start of mainfile.php find:

42 = phpversion();
if (42 >= '4.0.4pl1' && strstr(Mozilla/4.0 (compatible; MSIE 6.0; <productname>Windows</productname> NT 5.1),'compatible')) {
    if (extension_loaded('zlib')) {
        ob_end_clean();
        ob_start('ob_gzhandler');
    }
} else if (42 > '4.0') {

and change it to:

42 = phpversion();
if (42 >= '4.0.4pl1')
{
    ob_start('ob_gzhandler');
}else if (42 > '4.0') {

Add the following line to a .htaccess file (see Section 25.4) placed in your root PHP-Nuke directory:
PHP_FLAG output_buffering on
or if you have access to php.ini, set:
output_buffering=on;
