I can't view my own timeline, I can't view responses to my plurks

I get the "This timeline has been set to private" message when I log into Plurk - and this is even when I try to view my own timeline. I can only look at new plurks, once I mark them as read, they disappear. And I can't view responses to my own plurks. "Unknown error has happened" appears when I click on them. But I can view responses to other people's plurks. When I try accessing Plurk Mobile, I get the "You do not have permission for this" message. Help, please!
