Wordpress - Shareaholic

[Noare]

Hallo,

ich habe gerade das Plugin Shareaholic für Wordpress geupdatet. Allerdings funktioniert es nun nicht mehr, da keine Verbindung zum Shareaholic Server aufgebaut werden kann:

A network problem or firewall is blocking all connections from your web server to Shareaholic.com. Shareaholic cannot work correctly until this is fixed. Please contact your web host or firewall administrator and give them this information about Shareaholic and firewalls. Let us know too, so we can follow up!

Wie kann man das erlauben?
