Any ideas?

I am having same problem with "iso-8859-9".

I did not understand how I should configure regional settings and blog settings, or what do they stand for? There are two encoding settings, one is for Blog the other is for Settings->Regional.

Also, I don't know whether it is related to regional settings or not but I can not validate my blog on http://feedvalidator.org/

Waiting for your suggestions, otherwise I will have to use other blog softwares.

i have an idea... sorry for bad english.

_class_htmlchecker.php checks that your page is correct or not in standarts. maybe we can cheat...

open _class_htmlchecker.php and find
/**
* SafeHtmlChecker(-)
*/

/**
	 * SafeHtmlChecker(-)
	 */
	function SafeHtmlChecker( & $allowed_tags, & $allowed_attribues, & $uri_attrs, & $allowed_uri_scheme, $encoding = 'ISO-8859-1' )
	{
		$this->tags = & $allowed_tags;
		$this->tagattrs = & $allowed_attribues;
		$this->uri_attrs = & $uri_attrs;
		$this->allowed_uri_scheme = & $allowed_uri_scheme;
        $this->encoding = $encoding ;
		$this->parser = xml_parser_create( $this->encoding );
		$this->last_checked_pos = 0;
		$this->error = false;

when creating a new blog, i can select UTF-8 but cant iso-8859-9 so we can try show our encoding as UTF-8. change "$this->encoding = $encoding ;" string as following

$this->encoding = $encoding = 'UTF-8';

[/code]

it works in my site , good luck...

ok. Aj follow your instructions but i watch this error
