Unable to get "Unread Posts" to open
I have long used a bookmark called "Your Unread Posts for San Francisco Bay Area". It has always taken me directly to that site. Today I got instead a box reading "Sorry we can't find that page". I tried to re-access it but can only get the full SF Bay page with those entries both read and unread and with no way to mark those I have read so I don't get them again. I tried re-entering the URL, no luck. Searched Chowhounds including this Board, no luck. Then when I went to the full SF Board page, I tried to click on a link within one of the postings there, and instead of going to that link I was taken to the same "Sorry..etc." screen again.
What is going on and please help.
