I've been trying to like some HAs for the past half hour or so. When I click the heart, it turns pink, but if I navigate to another page and see the same person, the heart is black (and sad).

You just wanted more likes ;) Can you check now and see if it works? I just liked yours and it seems to have stuck.

- You can lock this up! I haven't had the problem since I posted about it :)

That is awesome! Glad to hear :D locking up!
