Remove Social Icons

Hi all!

I will Remove Social Icons (addthis – button) from the page. With “off” it does not work.
Whatever the reason this is so, I do not know.

Can you help me and write please: in which files I need to delete what?

i use the Directorypress and childtheme: blueplanet

Thank you!

* Sorry for my english… google translated 🙂

greetings from Germany
