// !!! IMPORTANT !!! If you are using permalinks to rewrite the urls
// of your site, you will need to adjust the action of the form below.
// The form will look for the wp-login.php file based on the action.
// If the rewritten url of your page is
// http://www.yourdomain.com/your_page_name/,
// you will need to change the action in the form to
// action='../wp-login.php'
// so it will look in the 'directory' above /your_page_name/
// for the wp-login file.
// Depending on your url structure, you may have to go up several directories.
// For instance, if your page is located at
// http://www.yourdomain.com/some_section/your_page_name/
// you will need to change the action to
// action='../../wp-login.php'
