You could try this:
php_value "output_buffering" "32000"
in the htaccess instead of:
php_flag output_buffering on

IF that doesn't work you might try adding this to the header.php
include("themes/$ThemeSel/theme.php");
ob_start(); // add this line
echo "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\">\n";

and this in footer.php
echo "</body>\n"
."</html>";
ob_end_flush(); // Add This line as shown
die();

This will probably work the best if you can't make output buffer changes to htaccess.

The file has to be named .htaccess not 1.htaccess. Was that just a typo?

.htaccess has blank line in end & start & Set permissions to 666
when I rename 1.htaccess file to .htaccess in public html folder with one of 3 line code , I have this error :

Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, webmaster@webdas.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

That's a whole different story and you should have told us that before Rolling Eyes

Anyway, Try adding this as your first statement to your .htaccess file. Only add one at a time, not both.

AllowOverride Options
or
AllowOverride All

If it allows that and doesn't return a 500 error, then add the
PHP_FLAG output_buffering On
line after that.

Before I look further, have you tried what I suggested in my last post?

AllowOverride Options
PHP_FLAG output_buffering On

or

AllowOverride All
PHP_FLAG output_buffering On

Posted: Sun Sep 19, 2004 12:14 pm

I test with
AllowOverride Options
PHP_FLAG output_buffering On

&

AllowOverride All
PHP_FLAG output_buffering On

but I have error 500 in 2 times

Please check with your host and find out if they allow .htaccess overrides. Not all hosts do although most do. Let's resolve the obvious before we try to resolve the rest.

In my host is empty .htaccess files in ever folders
I delete these ?

No. They don't hurt anything. Have you asked your host if they allow .htaccess overrides?

It is possible that your host is running PHP as CGI instead of an Apache module. Even so, you should not be getting a blank page. Refer to this post and try this method to see if that helps.
