404 Author Page for Admin

something odd is happening with my site… usually it will show an author’s posts and info if you click on their name, and it still does that but with all authors but me – the admin.

for instance, check out this post and click on ‘Mike Mineo’ (at the top): https://obscuresound.com/2010/12/destroyer-kaputt-2011/
there is nothing to be found. keep in mind that is the primary admin account.

but then look at this post, and click on the author ‘James Daly’: https://obscuresound.com/2010/12/interview-with-laura-imbruglia/
his page works

I understand it redirects to https://obscuresound.com/author/jdaly/ and jdaly is his user name to login, but my user name is plain old ‘mike’ and even going manually to https://obscuresound.com/author/mike STILL brings up a 404.

I imagine this can be fixed simply, I just don’t know how. not a huge issue, just an annoying one.

thanks.
