I play on the Plarium.com browser. The past couple weeks, when somebody in my BH gets Blockaded, I travel to their haven. On the map, it shows the haven not blockaded. I travel inside it shows he is blocked, but can't get the drop menu when my mouse is on him to show liberate. So I can't liberate my friend's haven. Usually, when I travel to a blockade haven, it shows on the map he is blockaded. When I travel inside his haven it should show the same, he's blockaded. Pass your mouse pointer on haven owners avatar and a drop-down menu appears containing amongst other things an option to liberate the haven.
