Unable to view past answers on my own profile
It’s not your own, it’s all answers (and questions) past the first page of results. See this thread: Why do I get the message “4?4 Oops, lost your way!” when I try to look at the next page of a user’s answers?
Certainly is frustrating.
Make sure you are logged in. Sometimes the system will kick you out without you realizing it, and you won’t be able to see past the first page.
But, as Paul says in the thread that Scott+Zelda linked to, there does appear to be some type of design flaw in the WordPress system that makes that happen sometimes.
If it ever works for you again, could you try copying/pasting the URL (internet address) here so we can see if something is different with it? I’ve tried investigating it from that pathway to see if I could manually get a fix, but no luck so far.
