One of my problems got two replies, so I went to check it out
It said this:
"Oops, page is not available
You may have mis-typed the URL. Please check your spelling."
I clicked on it from the watchlist
I just checked.
None of your questions have been whited out.
Maybe it was a temporary glitch.
If you click on your username and then on 'my profile' you will get access to all of your posts.
(Maybe not if they have been whited out or hidden but none of yours are whited out or hidden)
