Social buttons reset after changing domain name of website

Yesterday I changed the domain name of my website and noticed that all the social buttons in easyblog specially the facebook likes and shares are reset to "0".

Is there a way to get the facebook counts back? Like telling Facebook to use my old domain name?

This is my new domain name: http://www.tillahrens.de/
The old one was: http://www.astrologiehamburg.com/

Thanks

PS: there seems to be something wrong with my most popular post module.
It's called "Beliebteste Blogeinträge"
It's located directly under the post listings. It has 4 counts and 1 column.
The 2nd two counts there appears no introtext. Please check this for me!
