I just recently noticed that my site's Author Page results in a Not Found error (404 page).
Author Page: http://thefreeandeasyguidetopcs.com/author/PC.Guru/
Author Name: PC.Guru
It used to work just fine, not sure if a plugin in particular could have caused the problem.
What I tried:
1. Looking for any author related code in "single post.php" (just guessing here)
2. Successfully implemented this change (PC Guru to PC.Guru):
I did look through some support topics here but they don't help in my case. I've cross-checked most of them.
Any help would be appreciated.
