Edocman social buttons not showing

I've installed Edocman 1.5.7 onto a clean Joomla 3.3.3 install.

As can be seen from my attached image, only the 'Tweet' link displays. I have the configuration option selected in the Joomla administrator. Also, note the console, which shows that FB is not defined.

As I have not modified any code, I'm suspecting this is a bug.

Can you reply letting me know if there is anything else I need to do, or if this is indeed a bug - and, if so, a fix?

thanks

Sorry. Just realized what was happening.

I have the Chrome Disconnect extension installed an it was blocking the social sites - which is why the buttons weren't working.

Great. Thanks John for letting us know.
