Counter doesn't work

Hi.

First of all: Thanks for your great plug-in. I have a question though concerning the counters of the social buttons: I just tried to “like” my own blog news on facebook but nothing happens. Either the like counter on my site changes nor Facebook recognizes my “like”. I tried the same with Twitter – Twitter received my click – but still the counter does not count up.
Do you have an idea what the problem could be?

Thanks a lot. Johnny.
