Strange things have been happening lately.
1. Visited threads are still marked as unread ?
2. Even though I made the last post in this thread, php forum doesn't say so.
I have attached the screenshots of the forum and the thread.

One more bug. The url, http://www.daniweb.com/forums/online.php doesn't serve its purpose. When I click this url, all I get is
Screenshot attached.
And,
When I double click on the folder icon which on hover says, "Double-click this icon to mark this forum and its contents as read", it makes all the thread in the forum 'read' for time being. When I reload the page, some threads are back to 'unread' status again.

I have checked all these 'errors' couple of times just to make sure I wasn't dreaming (its 2 in the morning) .

Edit: What happened to my attachments ?

case solved. The site was down.

Sorry about that
