I was looking at unread posts, after reading, they was still on the unread list, no matter how many times i looked at them,
refreshed page, logged out & back in, went away abd come back 2hrs later & still same posts there,
tried the "mark all posts as read" button,
Session verification failed. Please try logging out and back in again, and then try again.
i did log out and back in, went off and come back & logged in, the read unread posts are still there, lol.
