Undefined offset and invalid arguments errors in theme settings page.

There seems to be some problems with drupal_http_request in your environment. Or the connection of your server to the bootswatch api server.

Should we add a check if the data is correct before we us the var in foreach?

like this?

 // Bootswatch.
  $bootswatch_themes = array();
  $request = drupal_http_request('http://api.bootswatch.com/3/');

if ($request is valid){

  $api = drupal_json_decode($request->data);
}
if ($api is valid) {

  foreach ($api['themes'] as $bootswatch_theme) {
    $bootswatch_themes[strtolower($bootswatch_theme['name'])] = $bootswatch_theme['name'];
  }
}

Thanks @jeremymcminn!

Hopefully this should fix the offset errors and provide a more useful error message. It sounds like your hosting server doesn't allow HTTP requests to be made, in this case, there is unfortunately not much we can do to get around that :(
