Button not working

I’ve downloaded the plugin, but the button does not work.

When I use the short code the icon is completely black. I cannot see the word “bloglovin” in it. I tried to change the color of the icon see if it would make a difference and it didn’t.

When I try to use the widget, it shows no button at all. In other words, all I see is the text link. I tried using all 3 options on the widget and none of them worked.
