I have installed this plugin to a site hosted with HostGator. I have confirmed that I my server is running PHP 5.2.13 with json and CURL running. I am using the "Self Domain" option to shorten links.
When I post a new blog entry nothing is going out to Ping. I have tested Ping.fm and it working. I am also not seeing any errors in the custom field.
What else do I need to do or change to fix this?
