|
 |
|
 Problem: You get errors of the form:
| Code: |
Warning: Cannot modify header information – headers already sent
|
when vieweing the forums.
 Solution 1: Near the start of mainfile.php find:
| Code: |
42 = phpversion();
if (42 >= '4.0.4pl1' && strstr(Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1),'compatible')) {
if (extension_loaded('zlib')) {
ob_end_clean();
ob_start('ob_gzhandler');
}
} else if (42 > '4.0') {
|
and change it to:
| Code: |
42 = phpversion();
if (42 >= '4.0.4pl1')
{
ob_start('ob_gzhandler');
}else if (42 > '4.0') {
|
Solution 2: Add the following line to a .htaccess file placed in your root PHP-Nuke directory:
| Code: |
PHP_FLAG output_buffering on
|
or if you have access to your php.ini, set:
| Code: |
output_buffering=on;
|
See Warning: Cannot modify header information on Forums and Cannot modify header information.

On my system the solution posted here did not work.
After messing around i found that this one worked.
(on php-nuke 7.1)
Enjoy

Paste this into the mainfile instead of the one above if the one above does not work.
| Code: | $phpversion;
if (42 >= '4.0.4pl1')
{
ob_start('ob_gzhandler');
}else if (42 > '4.0') { |

on my system, with phpnuke7.4, neither of these solutions work, and there is no .htaccess file in the main directory to modify...
the closest line to the above one that is to be searched for, is as follows...
| Code: |
$phpver = phpversion();
if ($phpver >= '4.0.4pl1' && strstr($HTTP_USER_AGENT,'compatible')) {
if (extension_loaded('zlib')) {
ob_end_clean();
ob_start('ob_gzhandler');
}
|
please, if you could, tell me what I must do to fix this, I tried removing from the && to the first ) and the "if (extension_loaded('zlib')) { ob_end_clean();" and then I get an error that's a total fail to load the page at all because of a miscompile or something to that effect. |

Fine. You can create one. 
A .htaccess file is not part of PHP-Nuke.

if ($phpver >= '4.0.4pl1' && strstr($HTTP_USER_AGENT,'compatible')) {

ob_start('ob_gzhandler');
}

OR try:
| Code: |
$phpver = phpversion();
if ($phpver >= '4.0.4pl1') {
if (extension_loaded('zlib')) {
ob_end_clean();
ob_start('ob_gzhandler');
}

The funny thing is I only see the error with Firefox 1.0 when I am logged in.
But solution #2 fixed it for firefox. |

if ($phpver >= '4.0.4pl1' && strstr($HTTP_USER_AGENT,'compatible')) {
if (extension_loaded('zlib')) {
ob_end_clean();

}
