I literally just installed the plugin WordPress SEO By Yoast and it recommended that I change my post path to be the Post Name. I did that and now I’m coming up with a 403 Forbidden message on the entire site. I can’t do anything.
For future reference, all you have to do is enter the Site Title or what you want as the copyright information where Site Title is in the theme editor. If you’re using an image for your title, then you just tell it to hide the title.
