This plugin isn’t working properly

Hi,

I like this plugin. Is a very simple idea and easy to use. But for me it isn’t working.
I’ve got three problems:
– The icons aren’t showing (only Facebook by default)
– The option “small” doesn’t work as well, I always get medium icons.
– The link doesn’t take you to the address, just get added to the address of the web.

I hope there is a solution to this issues.

Thanks for your work!!
