When you say you are no longer able to click to find other posts by a user, what happens when you try? Does the link appear in the menu by their username? I tried with yours and I was able to click it and see your posts. Hopefully it was just a temporary snafu, but please let us know what is happening
Btw, there have been some intermittent problems with the search feature that tech has been working on. It could be related.
