I had replied to a thread yesterday and am watching it. I got an alert about a reply posted by someone else to the same thread. However, today I am not able to view the thread. When I try to open the page without logging-in in my ac, a message appears stating 'You need to log in to view this thread.' When I log in and open the page again, another message appears that reads 'You do not have permission to view this page or perform this action.' I don't know what is wrong since yesterday I was able to view it. Also, the alert notification has been removed from my DP account but is there in my mail. Does this happen sometimes? I don't know as I am quite new to DP. Can someone please help or explain?
