Andrej,
You have the following CSS code loading on the site:
.login,
.element-invisible {
display: none;
}That's causing the entire social login area to not be displayed because we use a class of "login" on each of the social login buttons.
That CSS is found in the css/style.css file. You'll need to remove that code, or make it more specific to the element you actually want to hide.
I hope that helps,
Alex
