Author Info Page – Not Found

Hi Guys,

I just recently noticed that my site’s Author Page results in a Not Found error (404 page).

URL: https://thefreeandeasyguidetopcs.com

Author Page: https://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):
https://wphacks.com/change-author-archive-permalink/

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.

Thanks!
