In header.tpl I have
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>{$pagetitle}{if $kbarticle.title} - {$kbarticle.title}{/if}</title>
<meta http-equiv="content-type" content="text/html; charset={$charset}" />
<meta name="keywords" content="{$LANG.keywords}" />
<meta name="description" content="{$LANG.desc}" />
But in source I have only
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Portal Home</title>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<meta name="keywords" content="" />
<meta name="description" content="" />
What does it mean?
