Bug with internal links

Hi! There is a serious bug in this module: if the module enabled, all internal links does not work and look as some text. This bug is caused by function _ext_link_page_replace() in file ext_link_page.module.
So, i have corrected this bug, and you can see the full code of this function below.

function _ext_link_page_replace($match) {
  // Get defaults
  $defaults = _ext_link_page_get_defaults();
  $url = $match[1];
  $filtered = '';

  // If the link is external and valid and it's not an absolute link to the current site
  if (url_is_external($match[1])) {
    $filtered = url(
      variable_get('ext_link_page_link_page', $defaults['ext_link_page_link_page']),
      array(
        'query' => array(
          'url' => $match[1],
        ),
      )
    );
    $filtered = 'href="' . $filtered . '"';

    // Check if we want new window or nofollow
    if (variable_get('ext_link_page_new_window', $defaults['ext_link_page_new_window'])) {
      $filtered .= ' target="_blank"';
    }
    if (variable_get('ext_link_page_nofollow', $defaults['ext_link_page_nofollow'])) {
      $filtered .= ' rel="nofollow"';
    }
    
    return $filtered;
  }
  else {
  $filtered = 'href="' . $match[1] . '"';
  return $filtered;
  }
}
