Unfortunately the temporary directory /tmp may not set outside of the Joomla!-ROOT and allow_url_fopen must be on.
Temporary directory doesn't need to be set within Joomla! root it is just has to be writeable. Having it outside of the root can cause weirdness with permissions. allow_url_fopen is only required if you use the fopen method, using the curl option shouldn't require it.
