Hi,
what does the following error mean? It occurs after clicking the “Download button”. Thanks for any response! Kay

Warning: get_headers(): http:// wrapper is disabled in the server configuration by allow_url_fopen=0 in /kunden/548141_20354/webseiten/wordpress/wordpress/wp-content/plugins/sdm-squeeze-form/sdm-sf-shortcodes.php on line 159

Looks like this server is not allowing the call to the get_headers() function of PHP. Can you please ask your hosting provider why it is not allowing the call to the following function of PHP?
