after the last update of graphene i get the following error in the header:
Warning: getimagesize(): https:// wrapper is disabled in the server configuration by allow_url_fopen=0 in /kunden/221190_67281/webseiten/wordpress/wp-content/themes/graphene/inc/functions.php on line 39
This error appears if the allow_url_fopen is set to disabled in PHP. I would suggest either of these solutions:
1. Request your host to enable allow_url_fopen in PHP settings.
2. Disable PHP error display on your site.
