Warning: Cannot modify header information - headers already

Every now and then I get this error. So far I have only noticed it on Firefox.

Anyone know what it is?

Warning: Cannot modify header information - headers already sent by (output started at /home/amduser/public_html/themes/amdusers/theme.php:202) in /home/amduser/public_html/includes/page_header.php on line 492

Hmm. I the .htaccess one. I get a 500 Internal Server Error.

The mainfile.php trick isn't doing the trick for me.

And I don't think I have access to php.ini

Recheck the .htaccess. Usually, but not always, a 500 error means a syntax error. It won't hurt to try it again.

Raven,

Do I put this before everything else in the .htaccess file or at the end?

Just place it at the top

Hmm, I copied and pasted PHP_FLAG output_buffering On and I get the 500 Error... I don't know whats going on.

Check with your host. It could be that they don't allow PHP overrides, in which case you need to ask them to change it in the global php.ini.

it might be php_flag output_buffering On

That doesn't matter Smile

What exactly would I need to put in the blank file?
My host:

Quote:

PHP overrides is not a setting in the php.ini.

It likely refers to specific settings you are to override using your own php.ini.

To change the way php is handled, set the values in a php.ini file and place that file into every directory which needs the values you've set.

You're running PHP as a CGI and not an Apache module.

output_buffering = On;
