Broken permalinks

My permalinks are broken in that they are missing the /blog/ in the middle of the link, so everything redirects back to the main website and not to the blog page.

I tried adding it manually using a custom structure, but it just brings up an error for the whole blog. I can’t just change the permalinks for the whole blog because I just found out that earlier today USA Today linked to my blog. The link they have works, so I can’t do anything that would alter that link.

I can’t find an .htaccess file, even when hidden files are showing, so I’m guessing I don’t have one.

Any help would be very much appreciated
