if you have a root access to your domain then u can edit it from php.ini
if you do not but still are allowed for custom php input in your htaccess
you could try adding :
php_value allow_url_fopen 1
(into your .htaccess file ) or try 'On' instead of '1'

if neither solutions worked, let me know, i can substitue the fopen usage with curl which could be as much good and should work too.
