   Have you tried reuploading the core files (ie. everything except the wp-content folder)?

   Wait! just leave the entire wp-content folder alone, overwrite all the other files. If you only leave the themes folder, you could lose your plugins and uploads.

   Next step for me would be exporting the post content from the database, dropping the whole thing and reinstalling. Not sure if anyone else has a better idea?

    i dont know, it mentions some of the login.php content, the lines are the following:

    `// validate action so as to default to the login screen
    if ( !in_array($action, array('logout', 'lostpassword', 'retrievepassword', 'resetpass', 'rp', 'register', 'login')) && false === has_filter('login_form_' . $action) )
    $action = 'login';

    nocache_headers();

    header('Content-Type: '.get_bloginfo('html_type').'; charset='.get_bloginfo('charset'));

    if ( defined('RELOCATE') ) { // Move flag is set
    if ( isset( $_SERVER['PATH_INFO'] ) && ($_SERVER['PATH_INFO'] != $_SERVER['PHP_SELF']) )
    $_SERVER['PHP_SELF'] = str_replace( $_SERVER['PATH_INFO'], '', $_SERVER['PHP_SELF'] );

    $schema = ( isset($_SERVER['HTTPS']) && strtolower($_SERVER['HTTPS']) == 'on' ) ? 'https://' : 'http://';
    if ( dirname($schema . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF']) != get_option('siteurl') )
    update_option('siteurl', dirname($schema . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF']) );
    }

    //Set a cookie now to see if they are supported by the browser.
    setcookie(TEST_COOKIE, 'WP Cookie check', 0, COOKIEPATH, COOKIE_DOMAIN);
    if ( SITECOOKIEPATH != COOKIEPATH )
    setcookie(TEST_COOKIE, 'WP Cookie check', 0, SITECOOKIEPATH, COOKIE_DOMAIN);

    If you've replaced all the core files with freshly unzipped versions then the problem must be somewhere in the database, but I'm not sure where.

    That's why I'd just reinstall. Would you lose much data?

    i have no data, ive been working only with the design... if i reinstall fresh but keep a wp-themes folder, and then upload it, would i loose the advances in the layout design?

    No- the theme system is totally modular- you just upload your modified theme folder and select it in the admin. You'll have to define your categories etc again, but you won't lose any of your theme changes.

    What was the last change you made before the admin broke?
