Hi, I was confused at first but think I understand now... You're logged in (by saved cookies or whatever), and trying to change the password in the Profile > Account Settings section, right? Yeah looks like it needs current password (security feature for a device left unattended). But if you log out and then log in again, there is a forgot password option (on the main LuLa login as well as both forum login options). You may need to close browser or something to make sure it recognizes that you're logged out.
You might want to try it first from another device that is not logged in tho. That way if it gives you trouble and you need help, you can still use your logged-in device to post here. So I'd leave your current device logged in and use another device to try to change password.
